The most famous and top selling male sex toy in the world. Fleshlight looks like a flashlight but has a skin textured sheath on the inside allowing a penis to penetrate it.
There are various types of fleshlights ranging from vaginas, anus or even a mouth. The sheaths inside also come in several different textures like an ultra tight tunnel or a tight opening that opens into a wider tunnel to look like a vagina including the piece at the end that feels like a cervix.
Don't forget the golden rule when using these. Lube up.
