gay men like to fuck other men - they like to bend them over and bang them as hard as they can.
conversely, i've never had the remotest urge to fuck anything or anyone at all; i'm entirely sub, and have only ever fantasized about receiving vaginal sex.
further, gay men are attracted to other men, so they wouldn't be interested in me.
it consequently doesn't make any sense to tell me to just go be gay - not on either side of the equation.
