I think the emotional part is as big if not a bigger influence for women. My wife has said she isn't emotionally attracted to me at this time and it is why she doesn't want to have sex with me. I even got the "why would I want to have sex with you when...." Big list followed of things wrong with me in how I reacted to xxx, what I said, how I said it, etc... She didn't say anything about me physically but then maybe she just didn't get to it. I am working pretty hard to try to get the emotional and support end repaired and think/hope we've made some progress but I've got a ways to go to get to where your at - you had sex as much this weekend as I've had so far this year and that is actually an increase in activity for me from last year - so far.
