What's the difference between Realistic Butts and masturbation cups?

Written by: Bestvibe Published on September 04,2025

Preface

Hello everyone, today I want to talk about a topic that is often mentioned in American sex toy circles - Realistic Butts.

When many people first see the packaging of this product, they are attracted by the models or porn stars on the pictures, and some of them may think, “If I buy this sex toy, will I be able to experience the same feeling as the stars?”

Realistic Dildos

To give you a better idea of the category, let's talk in more detail about what Realistic Butts are, how they're made, and what sets this sex toy apart from other products.

What are Realistic Butts?

Simply put, Realistic Butts are sex toys that use molds to replicate the intimate parts of a real person's body, and then use materials such as TPE or silicone to create a sex toy that is so lifelike in shape and detail that it looks like a real butt.

In a way, Realistic Butts are not only sex toys, they can also be considered as a kind of mannequin.

Even in some Japanese sex education classes, teachers use these products as teaching props to demonstrate the body structure.

However, compared to ordinary masturbation cups, the biggest difference between Realistic Butts is that it is bigger and more realistic, and the reproduction process involves a real mannequin, and the production process is also more complicated.

How are Realistic Butts made?

Replicating a cunnilingus model

First, the manufacturer invites the model (who may be a pornographic actress or an ordinary person) and puts them in a position suitable for taking the mold.

To avoid the mold material sticking to the skin, a separator, such as petroleum jelly, is applied first.

Next, the blended material (often an alginate or silicone mixture) is evenly covered over the target area, making sure it fits perfectly and there are no air bubbles. Once the material has hardened, it is carefully removed and a complete negative mold is created.

This negative mold has all the details of the prototype recorded inside, from the texture to the shape.

Making the male mold

Once you have a negative mold, the next step is to pour the liquid silicone or TPE into the mold cavity.

This process requires shaking or vacuuming to remove air bubbles and ensure complete filling.

Once the gel has cooled and set, the mold is opened to reveal a “male mold”, which is the complete Realistic Butts entity.

After trimming, cleaning and coloring, the finished product is ready.

Many people may not know that a similar process is used for ordinary masturbation cups, except that instead of taking a mold from a real person, the mold is designed directly using 3D modeling.

How is the vagina part of Realistic Butts made?

One might wonder, since Realistic Butts is a life-size mold, is the inside of the vagina a direct copy?

Not really.

Most Realistic Butts' internal passageways are scanned and modeled in 3D.

Designers will use software to create different textures and tightnesses, and then combine them with mold production, which not only avoids harming the model, but also allows for more variations in functionality to give users a better experience when using this sex toy.

What is the difference between Realistic Butts and other sex toys?

On our Bestvibe, there are many kinds of sex toys, such as masturbation cups, vibrators, inflatable dolls, prostate massagers, etc. Compared with these products, Realistic Butts has several distinctive features:

Realistic Dildos

  • Larger size: unlike compact masturbation cups, Realistic Butts tend to be closer to the proportion of real people, and are heavier in size and weight.
  • More realistic: Realistic Butts are modeled after real people, so the shape, skin texture, and details are more lifelike.
  • More sophisticated materials: Most Realistic Butts use high quality silicone or TPE, which are soft, flexible and close to real skin.
  • Higher price: Due to the complexity and high cost of the process, Realistic Butts are generally more expensive than ordinary sex toys.

For users who like to pursue realistic experience, Realistic Butts is a good choice, but if you value portability or price more, ordinary masturbation cups may be more suitable.

What do I need to be aware of when using Realistic Butts?

Although Realistic Butts are designed to be realistic, there are some points to keep in mind when using them:

Realistic Dildos

  • Cleaning: Rinse the Realistic Butts with a special cleaning solution or warm water after each use to avoid the growth of bacteria.
  • Lubrication: Always use a water-based lubricant with your Realistic Butts to prolong the life of your sex toy and increase comfort.
  • Storage: It is best to keep it in a cool and dry place, avoiding direct sunlight or high temperature to avoid aging of the material.
  • Privacy: Realistic Butts are large in size, so it is recommended to prepare an organizer bag or storage box for easy storage.

Summary

In a nutshell, Realistic Butts is a highly simulated sex toy that derives its shape from a real person taking a mold and its internal channels are mostly modeled in 3D.

Realistic Dildos

It is more realistic and immersive than regular sex toys, but also more expensive and demanding to store.

If you like to pursue the sense of reality, these products are worth trying; if you value practicality and portability, other sex toys may be more suitable for you. Which one you ultimately choose still depends on your personal needs.
