Gay is here to stay. If it comes down to why you can't understand it, then maybe I could agree. I don't but I'm not afraid and I don't condem them. I don't understand many human behaviors. If there were no gay people, what other group would you focus on. Fat people? Gay people like everyone else want to be excepted. Because a man is straight doesn't always make him a better person. If it's the sex part that upsets you, then don't think about it. I bet there are some women out there that are married to men that hate having sex with them. You are looking at just the physical act, maybe there's more to it in a gay relationship than just sex. It's finding a person who excepts them for the way they are.
