P.S. Probably the most awesome sex book ever is "The Guide to Getting it On". Do you already know it? I wish I had a stack just to hand out to everyone I care about.
I'm not totally familiar with your whole situation so I don't know if it is even appropriate to share with your H, but if you decide at some point a book would be helpful to you, maybe as a way to start a conversation, this is extremely well-researched, light-hearted, and most of all, has the most helpful attitude about sex that I've ever encountered.
