Biologically it is just as correct as being Heterosexual. A man sticking his shwing in the anus of another man is no different in the act than from a man doing it to a woman, simply without the breasts and vagina. If it weren't, it wouldn't work as easily (or at all) as it does for a decent size of the world's population.Loop Stricken said:No, but it's still wrong.
Not morally; biologically. It's incorrect. I don't have a problem with it, it's just not cricket.
Now if you are stating from an entirely reproductive sense, then no.. it doesn't work that way.
