Have you ever dealt with, or known anyone who was dealing with sex addiction or hyper sexuality?

I've been told I suffer from it. I've never really dealt with it but I would say my sexual activity upsets some people. But I feel as long as I'm not hurting anyone and I have a good time and deal it back occasionally it's not a real problem.

I have dealt with other addictions (drink and drugs) so I know personally the damage addiction does.
