1. Most pussies certainly not all are made equal. Silicone is different than TPE, and built-in is different than insertables. All manufacturers create their own “spin” on lady parts. Position bias and internal stimulation canals can vary widely. This is partially why they can be so addictive. It is also why I usually recommend dolls with insertable vaginas. This lets you adjust or customize the feel by experimenting with 100’s aftermarket sleeves, onaholes, and other options. This lifestyle is all about experimenting, variations, and discovering what really works for you.
2. Lots of variation ranging from just a hole to ultra-realistic.
TPE doll pussies can look pretty good, but silicone is the medium for that “so real you can’t tell the difference look”.
