I'll give you my perspective as another Christian: According to the Bible, homosexuality is a sin, yes, but so is lying or having bad thoughts about people. In other words, it's not a huge deal because it's all just sin. If you're a Christian, you won't go to Hell, and God will help you with whatever strange feelings you may be having if you ask Him to. He understands. When I was younger, I thought I was very deffinitely bi, but over the years, God has taken that desire out of me. I still have occasional thoughts, but since we're human, we'll never be up to God's standard. That's why he sent Jesus Christ to purify us in God's eyes by dying for us. It's not something to worry about, really. Just keep praying and laying it on God, and He'll take care of you. I still like to look at a beautiful woman, but it's because she's beautiful, and not because I'm lusting over her.
Just don't stress about it, OK? Even if you act on your feelings, God would never send one of His own to Hell, and there are far worse crimes than homosexuality. I'll pray for you, too, because I know a lot of people have strong feelings of guilt about that kind of thing.
