Orifices
There are three orifice options on female sex dolls, (anal, vaginal, and oral) and two on male sex dolls (anal and oral). However, not all dolls will provide you with these options.
For example, WM Dolls Anastasia only offers anal and vaginal opportunities and Realdoll Stephanie 2.0 only has a vaginal opening. Sometimes you can customize them further, but you should think hard about what your favorite positions are before choosing a specific doll.
Breasts and hips
Sex dolls are meant to look fairly realistic but they also play out fantasies, so don’t expect realistic measurements. Breasts are often much larger than in real life while hips are on the petite side.
You can adjust breast size in any of the dolls except the inflatable.
Those wanting a very large breast experience will really enjoy WM Dolls Anna as she comes with M-cup breasts. Most other dolls, however, will offer choices from A-cup to D-cup.
Stimulation
A lot about a sex doll is focused on the outer appearance but the inner construction is just as important. Many models allow you to choose the texture of the vaginal or anal orifices, and the variety of inner textures can bring unforgettable orgasms. The inflatable Shy Camilla had different textures to choose from, as does WM Dolls Anastasia.
Durability
Sex dolls have amazing construction, so they should be very durable. While inflatable dolls, like Shy Camilla, are not as durable, other models are much more so.
Their steel skeletons and TPE construction allow them to withstand continued use.
Price
Because there are two main types of materials for sex dolls, the price can range drastically.
The cheaper alternative is inflatable sex dolls. For example, Shy Camilla only costs around $200. However, with TPE dolls, you can expect the low end to be around $2000 while the high end is $3000. The extreme would be with Realdoll Stephanie 2.0, as she starts around $5000.
Many sex dolls seem like they are somewhat affordable but once you start customizing them, or adding on extras, the price can greatly increase. These include storage cases and whether your doll has jelly breasts.
