I had one of those..
!!!
It would have been as bad if that was the way we started off, but he cooled down six months after we were dating. So the the remainder of the two and a half years we dated we must have had sex
3 times, although I only remember two of the ocassions, I will say three for arguments sake.
It was VERY frustrating, because he just cut me off cold with no real explanation other than "he didn't feel like a man", so for reasons that out weighed the sex issue, I left him to figure out what in the hell it was he actually felt like.
