An artificial vagina is also called a stroker, sleeve, masturbation aid, masturbator, or pocket pussy, and is a sex toy principally made for those with penises.
That is, these are adult devices designed to put the penis in, and that imitate the feel and sensation of having sexual intercourse with the female sex organ.
The internals of artificial vaginas are typically made from soft materials that imitate the feel of natural skin, besides of being stretchable and elastic to enable penetration or stroking for different penis sizes.
You can find many different types, styles, and functionalities of artificial vaginas, such as those with moving parts, vibrating, lubricated, heated, one-time use or multiple times, realistic, hand-held, sex-doll installed, and/or hands-free artificial vaginas, to give you the idea.
