Sorry, bottoming, i.e., receiving prostate stimulus, is not gay. It's simply receiving prostate stimulus. There are many, many gay guys who do not like receiving prostate stimulus, and there are straight guys who do like it. Probably a lot more who would like it if they did not have preconceived gay notions about it, basically because it's a go-to sexual position for gay guys. I know several guys who are 100% straight who like to play with vibrators on their prostate, either by themselves or with their wives or gf, but the smell, taste, or touch of another guy grosses them out and is a definite boner-killer. They are no more gay than the straight guy who beats off: he has a hard cock in his hand, and he's so aroused with that hard cock in his hand that he ends up with an orgasm. (He must be gay!)
