Nobody here is going to call you weird and the best that I can suggest is talking to a sex therapist about it.

Things change, we change. Maybe it was just a bad tme or outside pressures like a normal relationship is affecting you?...we couldn't tell you. But you are not weird. It's nothing that I would get worried about...sometimes our body runs the show. After all, we based a lot of our decisions on how our body reacts to things.

Sometimes when things that I do aren't appealing but later are...maybe just a phase? Then again, I really can't talk for a singleton to well. Sorry, but you are not weird.
