It's more than I let it ruin relationships. I seemingly only want it from someone I'm not involved with, and the guys I date are not the guys I want to have sexual relationships with. I just can't seem to mix the two.

I'm already divorced once and I'm under 30. I feel it's about to ruin my current relationship too, we've been together for 2 years. I can't talk to him about this though, which is a rather big problem. Ack.
