Well, first of all most boys that age commonly explore sexuality with other boys, but I thought they did this only with people they know very well and trust. You said these 2 guys are not that close, or so you think, which surprised me.
So, you might make your bf feel so comfortable about himself, and he may trust you so much (that's a compliment) that he feels he can explore this part of himself with you around. Better with you around than behind your back, right?
Anyway, it's probably just a phase, so don't worry to much about it. Plus, small possibility your bf might end up being bi in the long run.
At first I thought they might be kissing as a joke, or just to gross you out (boys like to gross out girls at that age). But then they were staring into each others' eyes. Maybe they are still trying to get a rise out of you.
Oh, he cheated on you with a transsexual prostitute, or a transvestite prostitute? Subtle difference there. Yeah he may be exploring his sexuality, and he may be bi. Are you ok with that? Or are you just angry he cheated on you? I think the big issue here is he did something behind your back, not that he also likes dudes.
Sexuality cannot be put into neat little boxes, like straight, bi or gay. Sexuality is a whole spectrum. Sometimes guys are mostly straight but they are curious about men. Simply because guys are very curious about all things sexual. Sometimes they are mostly gay, but are sometimes curious about girls.
p.s. Your bf is not confused, it sounds like he knows what he likes, and he likes boys and girls. However his cheating has to stop.
