M.H.
Can't say if it's medical or not, but try reading the Twilight books - no joke. They work great, even if you weren't feeling it before, they seem to do the trick and I know I'm not the only mom who's thought that. If you haven't read them, then do, and if you have then read them again. It's very cleanly written, no smut, but let's just say that most husbands really like it when their wives read these books. Good luck!
