Yes, women sometimes just want sex. I tried that a few times, when I met someone and we had great sex and I never even THOUGHT about relationship issues or anything. It was just for the fun.

BUT: How come I always waited for him to call the next day? How come I usually fall in love with the guy I slept with, even if this was not intended.

All I want to say is: Be careful. Now she says it's just for the sex and tomorrow she asks you to leave your wife...
