I've learned that the best way to figure out what your unique sexual orientation is, is staying away from porn for a long period of time. Sometimes, fantasies are just fantasies and psychologists now that a lot of straight male may have some gay fantasies sometimes, or at least curiosity. And, last but not least, learning to be tolerant about every sexual orientation. A lot of HOCD sufferers are not homophobic but come from very homophobic backgrounds (family, environment...). That what gives a lot of power to the anxiety, even if being gay or whatever is nothing wrong. And nobody here can tell another what his sexual orientation is. Be tolerant and accepting about everything that doesn't hurt anybody, cure your addiction and self-confidence issues and you will find yourself.
