Hi. Sorry this is so distressing to you. Would it surprise you to know that many 100 percent straight, never BEEN with someone of the same sex people actually fantasize about the same sex? Ya, it's a pretty common fantasy. It is erotic. Forbidden. And tantalizing. And they aren't gay nor will they become gay. It's their fantasy world and not something they act on. You have a boyfriend. Go with that. And try to just remember the thoughts in our head are not that serious. They are just thoughts.
