Heh, I still don't get the "But you have to like it to be gay LOL" thing. By that logic, a dude can willingly choose to suck a thousand wangs a day and as long as he doesn't like it he wouldn't be gay (Male prostitutes come to mind as examples of this)? Not buying it.
As a rule of thumb, if you take it in the pooper or suck wangs then you're gay. Exceptions being a) Raep b)Intoxicated (and still, that's pretty gay) or c) First time curiosity (more than once = gay/bi; even then it's still pretty damn gay, you don't get in on some dude on dude action for shits and giggles. You do it because you got some lust for wang going on). Oh, and d) Shemales/traps/whatever you call them, pre finding out that they have a wang. Post wang discovery = gay.
