I also find it difficult to interact with someone I find attractive. I often can barely talk to or be around anyone I find attractive. I don't know if it's just that I'm afraid they'll realize I find them attractive and they'll either be mad at me or ridicule me in some way or if there's more to it. Unfortunately, I'm usually attracted to people before I interact with them much so I never get a chance to have someone I'm attracted to get to know me. And since I'm ugly, the only chance I have is if someone is attracted to my personality and they can't be if I'm too terrified to even be in the same room as them.
