I did in college. We would do the nasty at her apartment and I would no sooner than roll off of her and she would say "are you ready to do it again?" I dated her for a few months but they were the best and worst months of my college life because of her insistence for sex. She was way over the top on sex. There are probably guys that could keep up but I could never keep up with her. I was glad when I moved away.
