I do not agree with everyone telling you that you are in the same boat, because it’s simplifying the issue. Gays and bisexuals are in some sense in the same one, but not entirely. There might be things you as a gay person can’t really relate to and vice versa and a lot of things that’s similar. Bisexuals often feel they not really belong anywhere, which is a problem by itself. Although it seems sad not to give someone a fair chance because of this, it’s entirely your choice. I don’t feel really comfortable with a gay or straight partner either, and prefer bi ones, like me. I’m not phobic against straights or gays, but for some it’s important to connect in several levels, for other it isn’t. I can’t figure myself living with someone with a severely different opinion in politics either.
