If you’re just starting to learn about sex toys, or you’ve recently started looking for your first dildo, one of the first questions you may have is not “Which one should I buy?” but rather: What exactly is a dildo?
Simply put, a dildo is a type of adult toy mainly designed for insertable use. It usually does not have a built-in vibrating motor and instead relies on its shape, size, material, and overall construction to provide different experiences.
Today, dildos are about much more than traditional realistic designs. You can find silicone dildos, TPE dildos, glass dildos, as well as products with different lengths, diameters, curves, and base designs. Different designs are suited to different situations, so choosing a dildo should involve more than just looking at its appearance.
What Is a Dildo?
A dildo is an adult toy that does not have a built-in vibration function. It is commonly designed with a shaft-like or realistic shape, although there are also plenty of non-realistic designs.
The biggest difference between a dildo and a vibrator is that a traditional dildo usually does not create vibration on its own. Instead, its size, shape, firmness, surface texture, and overall construction contribute to the experience.
Some dildos come with suction cup bases that allow them to be attached to a suitable smooth surface. Others are designed to work with a harness, while some are made specifically for different types of use.
So when you see the word “dildo,” it is better not to think of one fixed shape. Dildos are actually a fairly broad category of adult toys.
What Are Dildos Used For?
The most common use of a dildo is as an insertable adult toy. Some people also use dildos for personal exploration or as part of partnered sexual activity.
The differences between designs can be significant.
For example, shorter and narrower dildos made from softer materials may be easier for someone new to this type of adult toy to get used to. Larger designs may be more suitable for people with more experience who already know what they are comfortable with.
Some dildos also focus heavily on realistic details, such as realistic dildos, while others do not try to imitate the human body at all and instead use simple shapes or distinctive curves.
If you’re interested in the differences between these two approaches, Realistic vs Non-Realistic Dildos: Which Should You Choose? takes a closer look at how realistic and non-realistic designs differ.
That is why choosing a dildo should not come down to thinking that “bigger is better” or “more realistic is better.” What matters more is whether the product’s design matches your needs and preferences.
What Types of Dildos Are There?
There are many different types of dildos available today. Common categories include:
- Realistic Dildos: Designed to emphasize a realistic appearance and details.
- Non-Realistic Dildos: More focused on simple shapes and designs rather than trying to imitate the human body.
- Silicone Dildos: Very common in the adult toy market, with material feel, cleaning, and overall quality being important considerations.
- TPE Dildos: Usually known for being soft and flexible, giving them their own place in the market in terms of softness and price.
- Glass Dildos: Made with a rigid structure and offering a noticeably different feel and appearance from soft-material products.
- Suction Cup Dildos: Designed with a suction cup base that can attach to a suitable smooth surface.
- Harness-Compatible Dildos: Designed to be used with a compatible harness.
- Extra-Large Dildos: Significantly larger adult toys that are generally more appropriate for people who already understand their own comfort limits.
There are also curved dildos, double-ended dildos, anal dildos, and many other designs.
If a stable base is more important to you, Suction Cup Dildos for Beginners: Stable, Flexible, and Easy to Use explains what to look for in this type of dildo.
So, “dildo” is better understood as a broad category rather than one specific type of product.
Made from phthalate-free, latex-free, body-safe silicone that is flexible, waterproof, durable, and easy to clean.
What Are Dildos Made Of?
Material is one of the things worth paying attention to when choosing a dildo.
Some of the most common materials include silicone, TPE, and glass.
Silicone dildos are very common in the adult toy market. Different silicone formulations, firmness levels, and surface finishes can create noticeably different feels, so two products can both be silicone dildos and still feel quite different.
TPE dildos often emphasize softness and flexibility. Many feel more flexible than firmer silicone products. However, TPE and silicone also differ in areas such as cleaning, storage, and long-term use.
Glass dildos are a completely different category. They do not have the flexibility of soft materials, but their firmness, smooth surface, and ability to be shaped in different ways give them their own characteristics.
When comparing materials, asking which one is “the best” does not really tell you much. A more practical approach is to consider softness, cleaning, feel, durability, and budget together.

Made from soft TPE material for a comfortable yet firm feel, combining flexibility with lifelike texture.
Dildo vs. Vibrator: What’s the Difference?
This is one of the things that can be confusing when someone is new to sex toys.
The simplest difference is:
A traditional dildo usually does not have a motor, while a vibrator uses a motor to create vibration.
The main differences between dildos tend to come from size, shape, material, and construction. With a vibrator, you also need to consider things such as vibration patterns, motor strength, speed settings, noise level, and battery life.
Of course, some products combine both designs, such as dildos with built-in vibration.
So within the adult toy category, dildos and vibrators are not completely separate categories. There is some overlap between the two.
If you’re buying a sex toy for the first time, figuring out whether you are more interested in an insertable design or vibration can be more useful than immediately focusing on a brand or appearance.
Who Might Consider Using a Dildo?
There is no single type of person who uses a dildo.
Some people prefer realistic dildos, while others care more about softness. Some focus on size, shape, or the way a dildo can be positioned or secured.
For someone buying a dildo for the first time, size is usually more important to think about than appearance. In particular, there is no need to start with an extremely large product.
If you’ve used adult toys before, you can narrow down your options by looking at the material, length, diameter, shape, and firmness you already know you prefer.
Personal use and partnered use can also call for different designs. Some dildos are better suited to use with a harness, some are designed for handheld use, and others include a suction cup.
How Do You Choose the Right Dildo?
When you start looking at dildos, there are a few basic specifications worth checking:
Size — This includes overall length, insertable length, and diameter.
If you’re unsure how these measurements affect your choice, How to Choose the Right Dildo Size? Complete Guide to Length and Girth explains the main differences between dildo length, girth, and overall size.
Material — Common options include silicone, TPE, and glass. Different materials have different levels of softness and different maintenance requirements.
Shape — Realistic, curved, straight, textured, and other designs can create different experiences.
Base — If you want a dildo that can be secured during use, look at suction cup dildos and other designs with stable bases.
Experience level — If this is your first dildo, focus on the size and firmness you are comfortable with rather than simply choosing the largest option.
Once you know what type of dildo you want, comparing size, material, and individual products becomes much easier than trying to choose from a large selection of adult toys all at once.

Final Thoughts
Dildos are a large category of adult toys. From simple silicone dildos to realistic dildos, TPE dildos, glass dildos, suction cup dildos, and products with different sizes and specialized shapes, the range is much broader than many people expect when they first come across the category.
If you simply want to understand what a dildo is, the most important points are these: it is an insertable adult toy, traditional designs usually do not have a vibrating motor, and the biggest differences between products come from size, material, shape, and construction.
Once you have a better idea of which type you actually want, moving on to specific size, material, and product choices becomes much easier.
FAQ
Not exactly. A traditional dildo usually does not have a vibrating motor, while a vibrator mainly uses a motor to create vibration. However, some dildos also include vibration, so the two categories can overlap.
No. Realistic dildos are only one type. There are also many non-realistic dildos that focus more on shape, curves, materials, or functional design.
Silicone is a very common material in the adult toy market, but TPE and glass also have their own user bases. There is no simple “best” material. The right choice depends mainly on the product design and personal preference.
For a first purchase, it is worth paying attention to size, material, firmness, shape, and cleaning requirements. There is usually no need to start with a very large size or a product with complicated features.
A larger size does not automatically make a dildo more suitable. Length, diameter, and insertable length should all be considered based on personal experience and comfort.
Cleaning depends on the material and the manufacturer’s instructions. In general, check the product’s care instructions before using soap, cleaners, or other products. Pay particular attention to the material and any seams, textured areas, or moving parts that may require additional cleaning.
