A gay thing? Really? When I think Fleshlight, I'd say the demographic is more for straight men than gay men. After all, the most famous Fleshlight and most of the Fleshlight designs are shaped like vaginas. They DO have some butt Fleshlights, though, and some mouths, too, though the mouths appear feminine, in my opinion. I recently found a Fleshlight Liberator piece, though, that could hold two Fleshlights on either side and featured two men using it and kissing so I guess they sometimes target gay men, as well. I'd say overall, they target straight men (take, for example, the line of Fleshlights modeled after female pornstars) but they also include gay men. Fleshlights are for men! Just masturbate and enjoy! Lol.
Heck, they even occasionally target women, what with the monster-themed dildos to go along with their monster-themed Fleshlights.
