So- you don't think of being gay as an appetite. So the problem is not your orientation.
Maybe t's time to look at the furniture in your head- that is- your beliefs. Are they helping you to be a more loving and peaceful person? If they aren't, then maybe it's time to adjust them, even get rid of them. Replace it with something better.
That said, it can be hard to let go of beliefs that one has had for a long time, only because one can become so identified with them that it can be hard to think of one's self without them.
But guess what? Being gay isn't a belief. It's a reality. Beliefs? They can change.
But don't fear. There are lots of folks who understand that being gay, and being a person of faith, is not a mutually exclusive thing. You aren't alone.
Be the love you seek.
