If you're initiating 5-7 times/week, and only being turned down 3-4 times/week, that's a 1-4/week times/week frequency - which isn't anywhere near a sexless marriage. Just because she doesn't want it AS much as you doesn't mean she doesn't want it, or enjoy it, or there's anything wrong with either of you. It's just a difference in drive. The only thing that might be a "too much" about it, is if you can't accept that she doesn't want it as much as you and make it a problem.Well, we are over that age range but I know what you are saying.
And I am sure something is wrong that she doesn't want it more...unless its me??? Maybe I want it too much?
