I did, for ten years. Unfortunately she was the first woman I'd been with, so I didn't even realize how inadequate the sex was until we were divorced. Okay, I wasn't happy about the lack of variety or her strict time limit, but had no idea other women were so much more responsive. Forgive my rambling, but the point is that you're not the only one who's had that problem. I don't really have any great advice, but good luck.
