There are gay or bisexual men who love or like anal sex, it’s true. But there are also gay or bisexual men who don’t like it, or who just aren’t interested in it. There are heterosexual men who don’t like anal sex or aren’t interested in it, either. There are also heterosexual men who like or love it. And for all of these groups, all of that goes for being on either end of anal sex, as it were, and for people with partners of any or every gender. Human sexuality is incredibly diverse, and all someone liking a given kind of sex can usually tell us by itself is that someone likes that kind of sex. That’s it.
Whether or not someone of any gender is curious about, wants, fantasizes about or takes part in anal sex in any way doesn’t tell us a darn thing about their orientation. Now, if and when a guy fantasizes about it, wants or or engages in it with other men, then that is an indication that guy probably is attracted to other men (though maybe not just men: being attracted to other men doesn’t always mean only being attracted to men), but that’s still not about anal sex specifically. That same guy might also feel that way about kissing and who he kisses, but if he told people he was interested in kissing — just kissing, not kissing any given gender of people — you wouldn’t hear anyone suggesting that probably means he’s gay, right?
