Well, I don't mean to be a party-pooper, but before a book should be considered as valid in a relationship, both parties need to agree to that. If not, then one partner is liable to think the other is going-behind-their-back, for whatever reason. I ain't a shrink, but have seen enough couples bust up over sex, or lack thereof, or any of a dozen other reasons, when the actual reason had nothing to do with it at all.
Isn't it just easier to be best friends before marriage and continue on, so that any little thing like a decrease in sex drive, can be rationally talked about?
There.
Got all of MY talking done with for the year!
(audience cheers!!!)
