While going online to one of those "hook" up sites might sound like a good idea, I personally wouldn't do that. It's the same for heterosexuals, you don't really know who you are talking to, or anything about them. You can pick up some real freaks that way.
Are there any "gay" bars where you live? At least you can see who you're talking with and decide for yourself if this is something you want.

Just a thought.
Good luck.
