I just read your response to my supply and demand theory. I want to clarify something: I know there are ladies that can hold out forever. My H could too. Thats why this relieve the pressure appoach won't work unless the couple has had plenty of conversation and work through MC or whatever. The agreement needs to be in place, the work done (on the issue of sex) Then... try the back off game.
In the early days of our problem, this approach totally backfired, we have been working hard for the last six months. I made him start talking. No matter how uncomfortable it was. This was validated by the MC. Which sort of gave me permission and took away the last few doubts about my rights to good sex.
The wemon ya'll mention don't sound like they believe how important good sex is yet. For my man to understand, it took a serious threat that I was leaving him. (and it wasn't an empty threat) As much as I love him then and now and always, I knew our marriage was dying, I didn't have a choice. It was get him to start talking or I had to leave. The choice was really his.
Please don't make the mistake that wemon are somehow harder to deal with; both men and wemon will usually respond when they finally know your serious.
