The punch line was... she DID like sex. A LOT! She liked it dirty. But she didn't want to be that intimate with her husband - the prospect scared her to death, because of what he might find OUT about her - she'd have to be vulnerable, and couldn't handle that.

Wow. I think that sums up my H pretty much. He has a very hard time being vulnerable but I also know he likes sex so there is a conflict in his head most of the time.
