This customer sums it up best with "I've just christened my doll and I fear I may never want to leave the house again". If you're familiar with the joys of a fleshlight, the physical feeling is similar only you have a full-body experience, with a healthy imagination, the realism is out of this world. Both the insert vagina and the built-in vagina are designed to give you the most realistic feeling of a woman's vagina possible. The anus and the mouth are also designed with as much realism as possible. All openings have ribbed areas to increase pleasure and the vagina has multiple "chambers" as you advance along it. On some models, a tongue can also be added to the mouth, if you wish, to enhance the oral experience.
