I have this problem where I lose sexual interest in any girl that I am dating for a while. I was like an animal with my new GF and now I am already losing interest in that area and find myself preferring to just talk and hang out together and kiss more than sex even though she's beautiful. She has a very big sex drive. I still have sex with her very often...but I can't seem to stay up for that long...I lose interest quickly. Has this ever happened to any of you? It's starting to get to me.
