If you feel that level of disgust about who you're attracted to (yes, I would think from what you say that you are bisexual) just remember, you decide what you do about it. You can just go with girls, even if you feel attracted to men. As a Christian, although you don't say what religion you are, I would say that if you feel that God doesn't look well on being gay or bi, look on it as a test, He tests people all the time. Resisting will make you feel better about keeping to your religion, but I'm afraid you can't hide who you are from yourself. You have to deal with who you are, you can't supress it, but you don't have to do anything about it.
