This was the first time I ever had a one nighter. I am 21, and going into senior year of college. This guy is going home in 4 days to Europe. It was a lot of fun and I was safe about it and used protection. He mentioned seeing me again before leaving. What do I do? I don't think I want to have sex again with him just because we already did it. At least not right away, because I don't want to like him too much. Besides he is going home soon anyway. What should I do?
