The Fleshlight was designed by Steve Shubin who was granted a patent in 1998 for his invention, as a "device for discreet sperm collection", and is marketed by Interactive Life Forms. It is named for the flesh-like material used in its inner sleeve, as well as the plastic case that houses the sleeve, which is fashioned to look like an oversized flashlight. The inner sleeve is available with vulva, anus, or mouth orifices, and comes in colours of flesh from a variety of ethnicities, as well as see-through, and 48 different internal textures.
The Fleshlight Girls brand consists of masturbation sleeves moulded from the bodies of female pornstars. A device called the Fleshjack is a spinoff marketed to homosexual men. The Fleshjack Boys brand consists of masturbation sleeves and dildos moulded from the bodies of gay pornstars.
