TPE sex dolls are more realistic and affordable, but require a lot of maintenance and may not be the best choice for vaginal owners due to hygiene risks.
Silicone sex dolls are more durable and easier to clean, but it's also more expensive, and the skin texture may not be as realistic as one might think.
The good news is, there are no wrong answers either! No matter what you choose, you'll have a lot of fun. As long as you take good care of your adult love doll, you'll have a great time.
If you're not sure which material is right for your needs, it's a good idea to "test" a few things. For example, if you like silicone dilators, you probably also like silicone dolls, as does TPE.
You can also buy half dolls, discount sex dolls, torso, butt or penis inserts. All of these products cost less than a full-size sex doll. Experiment with different materials to see which one works best for you.
Ultimately, there is no "better" option - it all comes down to what you want, need and can afford.
