Discovering Toy Types and Shapes – The Key to Making the Right Choice

Anyone exploring the world of sex toys will quickly encounter a wide variety of shapes and names. Dildos, anal plugs, and specially shaped toys each serve different purposes and offer distinct sensations.
In this guide, you will learn about the most important types and shapes of toys, as well as their typical characteristics. You will also discover which shapes suit different desires and what to look for when making a choice. Finding the right size is also crucial, though this topic is covered in detail in the guide "Finding the Right Size."

What is a dildo?

A dildo is a sex toy designed for either vaginal or anal penetration. Depending on its shape, size, and material, it creates different sensations and is suitable for various types of play. Dildos vary in terms of length, diameter, shape, and surface texture. While some models are designed to look as realistic as possible, others deliberately feature simple or ergonomically optimized shapes. Curved shafts, textured surfaces, or differently shaped tips can also influence the sensation during use.
Choosing the right dildo depends on more than just size; the desired type of stimulation, personal anatomy, and individual preferences are equally important. That is why it is worth taking a closer look at the different dildo shapes and their characteristics.

Typical structure of a dildo

Although dildos can differ significantly in shape and design, most models share a similar basic structure. The various parts influence how the toy feels and the type of stimulation for which it is best suited.
The tip makes insertion easier and often determines how precisely specific areas can be stimulated. Depending on its shape, it allows for smooth gliding or more intense, targeted stimulation. The shaft forms the main body of the dildo. Its length, diameter, and shape have the greatest impact on the sensation of fullness and the type of stimulation. A straight shaft usually provides a different sensation during use than a curved or textured model.
Many dildos also feature a base that serves as a handle, making them easier to use. For dildos suitable for anal use, the base also performs a crucial safety function by preventing the toy from being inserted entirely into the body.
These individual features can vary significantly depending on the style of play. You can learn about the available dildo shapes and designs—and which needs they suit—in the following chapters.

What is an anal plug?

An anal plug is a sex toy designed specifically for anal use. Unlike a dildo, it is not primarily intended for thrusting movements; instead, it is designed to remain comfortably and securely inside the body after insertion.
Its typical shape differs significantly from that of a dildo. Anal plugs generally feature a rounded or tapered body, a narrower neck, and a wide base. This design facilitates insertion, ensures a secure fit, and prevents the plug from slipping entirely into the body.
Depending on its shape and size, an anal plug can serve various purposes. Some models are particularly suitable for beginners, while others provide a more intense sensation of fullness or are designed for prolonged wear. Special shapes for targeted stimulation of specific areas are also available.
You will learn about the different designs, how they differ, and which ones suit specific preferences in the following chapters.

Typical structure of an anal plug

Although anal plugs vary in size and shape, most models share a similar basic structure. Each section performs a specific function, contributing to comfort, stability, and safety.
The tip is usually rounded or slightly tapered. This allows for comfortable insertion and enables the body to gradually adjust to the increasing diameter.
The body constitutes the main part of the anal plug. Its shape, maximum diameter, and length largely determine the sensation of fullness.
The neck is located between the body and the base. It is narrower than the plug itself, allowing the device to sit comfortably and securely behind the sphincter muscle after insertion. The base prevents the anal plug from slipping entirely into the body. At the same time, it facilitates safe removal, making it an essential safety feature.
These individual sections can vary significantly depending on the specific shape. In the following chapters, you will learn about the different shapes and designs of anal plugs and which preferences they cater to.

Understanding Shapes and Surfaces

Beyond the basic design of a toy, its shape plays a crucial role in the type of stimulation it provides. Among other things, the shape influences how easily the toy can be inserted, the sensation of fullness it creates, and which areas of the body are targeted.
However, shape never acts in isolation. The actual sensation during use emerges from the interplay of size, firmness, surface texture, and individual anatomy. Therefore, it is worth considering a toy's shape in the context of its other characteristics.
Surface texture also contributes to the experience. Some people prefer completely smooth toys, while others find textured surfaces particularly appealing. Both types have their own specific qualities and—depending on shape and personal preference—can provide different kinds of stimulation.
In the following chapters, we introduce the most common dildo and anal plug shapes, as well as various surface textures. This will help you determine which features best suit your personal preferences.

Common Dildo Shapes

Dildos come in a wide variety of shapes. They differ not only in appearance but also in how they feel during use. Depending on the shape, a dildo can target specific areas more precisely, create a different sensation of fullness, or be suitable for different types of play.
Straight dildos are among the classic shapes. They are versatile and suitable for both vaginal and anal use. Their uniform shape provides a balanced and easily controlled sensation.
Curved dildos feature a bent shaft. Depending on how they are positioned, this allows them to target and stimulate the G-spot or the prostate more effectively. Many users appreciate this shape for the precision stimulation it offers.
Tapered dildos narrow toward the tip. This makes insertion particularly comfortable, while the gradually increasing diameter intensifies the sensation of fullness step by step. This dildo shape is often suitable for those who prefer gentle insertion. Textured dildos feature ribs, ridges, beads, or other surface patterns. They provide extra stimulation, setting them apart from smooth models. The intensity of the sensation depends on both the nature of the texture and the chosen firmness. Which dildo shape suits you best depends on your personal preferences and the type of stimulation you desire. It is therefore worth exploring different dildo shapes and comparing their features.

Common Anal Plug Shapes

Anal plugs vary not only in size but also in shape. Depending on the shape, they may be easier or harder to insert, provide a different sensation of fullness, or be particularly well-suited for specific types of play.
Classic anal plugs feature a more or less evenly tapered, teardrop-like shape. They are comfortable to insert and sit securely behind the sphincter muscle once in place. This shape suits many users and is among the most popular varieties. Spherical anal plugs are also considered a classic design; while they offer a similar sensation of fullness, the abrupt transition to their widest point often makes them slightly more difficult to insert.
Curved anal plugs have a curved body. This allows them to target and stimulate the prostate more precisely—especially in men. Consequently, many users value this shape for the intense, pinpoint prostate stimulation it provides.
Long anal plugs feature an elongated body and—depending on the model—extend much deeper into the rectum than more compact designs. This shifts the sensation of fullness further inside the body. Many users find this deep sensation to be the unique appeal of this type of plug.
Which anal plug shape suits you best depends on your personal preferences and the type of stimulation you desire. It is therefore worth exploring the different shapes available and comparing their characteristics.

Smooth Surfaces

In addition to shape, surface texture has a noticeable impact on the sensation during use. Smooth surfaces are among the most popular options because they feel pleasant and are highly versatile.
Thanks to their uniform texture, smooth silicone toys glide easily over the skin and are generally comfortable to insert. Many users appreciate the consistent, easily controlled stimulation that smooth surfaces provide. Another advantage is ease of cleaning. Since residues rarely get trapped in crevices, smooth silicone toys are particularly easy to clean and maintain hygienically.
If you prefer a consistent sensation or are looking for a highly versatile toy, a smooth surface is often the ideal choice.

Textured Surfaces

Textured surfaces differ from smooth ones by featuring intentionally incorporated ribs, waves, beads, or other shapes. These create additional sensations and can intensify pleasure.
Depending on the design, these textures may be felt with varying intensity during insertion, withdrawal, or movement. Some people appreciate the varied stimulation, while others prefer a surface that is as smooth and uniform as possible. Which option feels better depends primarily on personal preference.
The intensity of a textured surface is determined by more than just its shape; the size, spacing, and prominence of the individual textures—as well as the material's firmness—also influence how distinctly the additional sensations are felt.
Whether a smooth or textured surface suits you better depends on your personal preferences and the type of stimulation you desire.

High-gloss or matte silicone surfaces

In addition to shape and texture, silicone toys also differ in their surface finish. Depending on the manufacturing process, they may feature a high-gloss or a matte finish. This does not affect material quality—both versions can be made from the same high-quality platinum silicone.
High-gloss surfaces look particularly premium and feel very smooth. They reflect light more intensely, giving the toy an elegant appearance. Many users also find them to be exceptionally silky to the touch.
Matte surfaces, on the other hand, have a more understated and natural look. They feel slightly velvety and offer a bit more grip, which some users find makes the toy easier to hold.
Which surface suits you best is primarily a matter of personal preference. Neither the glossy nor the matte finish is inherently superior. Both versions—provided they are made of high-quality platinum silicone—offer the same material quality and differ mainly in their look and feel.

Understanding size specifications

Size specifications play an important role when buying a sex toy. Terms like total length, insertable length, diameter, or circumference may seem straightforward at first glance, but in practice, they are often interpreted in different ways. To better compare different toys, you should know what these specific measurements actually mean and how they affect usage. After all, not every listed length is fully inserted. Furthermore, diameter and circumference essentially describe the same dimension—just in different ways.
In the following sections, we explain the key size specifications and highlight what to look for when comparing different toys. You can find detailed information on how to interpret these measurements to choose the right toy size in our guide, "Finding the Right Size." [05]

Total Length

Total length refers to the full length of a sex toy—measured from the tip to the end of the base or handle. It indicates the product's overall dimension, regardless of which part is actually inserted during use. Especially with anal plugs and dildos featuring a wide base or handle, the total length often differs significantly from the actually usable length. How far a toy can actually be inserted depends on its design; for this assessment, "insertable length" is the far more informative measurement.

Insertable Length

The insertable length indicates which part of a sex toy can actually be inserted into the body. For practical use, this is usually a much more meaningful figure than the total length. With anal plugs, in particular, the insertable length ends where the neck begins or the base attaches. For dildos, it often corresponds to almost the entire length, provided there is no prominent base or handle.
When comparing different toys, you should therefore focus primarily on the insertable length. It provides a much more realistic idea of ​​how deep a toy can actually be inserted.

Diameter and Circumference

Diameter and circumference describe the same dimension of a sex toy—they simply provide different measurements of the same cross-section. While the diameter indicates the distance from one side to the opposite side, the circumference describes the distance around the toy.
Since the two values ​​are directly related, the circumference can be calculated from the diameter at any time. An extra centimeter in diameter might initially sound like a small difference. In reality, however, this corresponds to an increase in circumference of around 3.14 cm. During use, this change can be perceived as a significantly stronger stretching sensation. Consequently, even a relatively small change in diameter can noticeably affect the sensation of pressure or stretching.
At Spielwerk, we list the diameter and, in most cases, the circumference as well. The diameter is easier and more straightforward to measure, allowing for a quick comparison of different models. If you prefer working with circumference or already have experience with this measurement, you can find the corresponding value in the table below.
 

diameter	Circumference (approx.)
3,0 cm	9,4 cm
4,0 cm	12,6 cm
5,0 cm	15,7 cm
6,0 cm	18,8 cm
7,0 cm	22,0 cm

It is also important to note that the stated diameter always refers to the toy's actual dimensions. However, how large a toy feels during use also depends on factors such as shape, material, and—in particular—its firmness.

Which shape suits which type of play?

There is no single toy shape that is equally suitable for everyone. The shape that suits you best depends primarily on what you want to achieve. Do you want a toy that is easy to insert, one that targets specific areas of the body, or one that provides a particularly intense sensation of fullness? Different characteristics may be advantageous depending on the intended use.
In addition to shape, factors such as size, firmness, and material play an important role. It is the interplay of these characteristics that determines how a toy actually feels during use. Therefore, it is worth considering the toy as a whole package rather than focusing on just one single feature.
In the following sections, you will learn which toy shapes are best suited to different preferences and what to look for when making your choice.

For beginners

If you are using a sex toy for the first time, you will usually benefit from a shape that is simple and easy to control. The goal should be to get to know your body and gain some initial experience—not to try out the largest or most unusual toys available.
For beginners, smoothly shaped dildos or anal plugs with moderate dimensions are generally the best choice. They are usually easier to insert and provide sensations that are pleasant and predictable.
Firmness also plays a role. Many beginners find softer silicone more comfortable, as the toy can adapt better to the body. However, the best choice regarding firmness and size always depends on individual anatomy and personal preferences.
A balanced combination of shape, size, and firmness creates the ideal conditions for a relaxed introduction.

For vaginal use

Many different dildo shapes are suitable for vaginal use. The shape that suits you best depends primarily on the type of stimulation you prefer and which areas you wish to target.
Straight dildos, in particular, allow for consistent stimulation and offer great versatility. Curved dildos, on the other hand, can target the G-spot more precisely, which some users find creates a particularly intense sensation. The shape of the tip, as well as a smooth or textured surface, also influence the sensation during use.
Naturally, size and firmness play an important role alongside shape. Softer silicone conforms more closely to the body, whereas a firmer model can allow for more precise and targeted stimulation.
Ultimately, there is no one-size-fits-all recommendation. The easiest way to discover which combination of shape, size, and firmness suits you best is to explore your personal preferences and experiences step by step.

For Anal Play

Both anal plugs and dildos are suitable options for anal play. Which type of toy is best depends primarily on what you want to achieve.
An anal plug is particularly well-suited if you want to enjoy a pleasant sensation of fullness or wear the toy for an extended period. It can also be a good choice if you want to gradually work your way up to larger sizes. Thanks to its characteristic shape, it stays securely in place behind the sphincter muscle after insertion.
A dildo suitable for anal play, on the other hand, is the better choice if you want to actively move the toy or target specific areas for stimulation. Depending on the shape and length, this can create a variety of sensations. It is always important to ensure the toy has a sufficiently wide base so that it cannot slip entirely inside the body.
Ultimately, the shape that suits you best depends on your anatomy, the type of play, your experience, and your personal preferences. Many users therefore utilize both anal plugs and dildos—each for different kinds of play.

For G-Spot and Prostate Stimulation

Anyone wishing to specifically stimulate the G-spot or prostate often benefits from a toy with a slightly curved shape. This curvature allows pressure to be directed precisely at these highly sensitive areas.
In addition to shape, the level of firmness plays an important role. Firmer silicone retains its shape better, which can allow for more precise application of pressure. A softer material, conversely, conforms more closely to the body and is often perceived as gentler.
However, the best choice regarding shape and firmness always depends on individual anatomy, personal preferences, and the desired type of stimulation. That is why it is worth exploring different combinations and gaining your own experience.

For experienced users

As users gain experience, their personal preferences often change. There is frequently a growing desire to try out new shapes, experience more intense sensations, or target specific areas for stimulation.
Consequently, experienced users often opt for larger toys, more pronounced textures, or specially shaped models. Longer dildos or unusual designs may also become appealing. However, the goal is not simply to choose ever-larger dimensions, but rather to find the toy that best suits your specific desires.
If you already know exactly which features matter to you, you can deliberately combine shape, size, firmness, and surface texture. This allows you to select a toy that is ideally suited to the kind of play experience you are looking for. Even with extensive experience, the rule remains: the best choice is not necessarily the largest or most unusual toy. What truly matters is that all the features are well-balanced and align with your personal preferences.

What impact does the level of firmness have?

The level of firmness significantly influences how a sex toy feels during use. Softer silicone conforms more closely to the body, whereas firmer material holds its shape better and is often easier to maneuver with precision. The right level of firmness depends on the toy's shape, the intended type of play, and your personal preferences. Therefore, firmness should always be considered in conjunction with size and shape.
You can find detailed information on the differences between firmness levels and their specific characteristics in our guide: "Platinum-Silicone Toys – Material, Firmness, and Quality."

Why quality matters

Shape and size aren't the only factors determining whether a toy provides long-term enjoyment. High-quality materials, careful craftsmanship, and the manufacturer's experience are equally important. It is the interplay of these factors that ensures comfort, durability, and consistently high quality.
We also explain what to look for when buying and the quality features that distinguish premium silicone toys in the guide: "Platinum-Silicone Toys – Material, Firmness, and Quality."

Conclusion

The shape of a sex toy significantly influences how it feels during use. Whether it’s a dildo or an anal plug, straight or curved, smooth or textured—each shape has unique characteristics and suits different desires and styles of play.
It is also important to correctly understand the size specifications. Only when you consider shape, size, firmness, and quality together can you select a toy that truly meets your needs.
Knowing the different types of toys and their characteristics makes choosing much easier. You can find detailed information on materials, firmness levels, and how to choose the right size in the relevant articles within the guide. This allows you to select—step by step—the toy that best suits your personal preferences and will bring you long-term enjoyment.
