Before I read the SSM book, I had a talk with my wife about her and my expectations for married sex. up to that point for the past 3 years we had sex maybe once every three months, with a long period, maybe 9 months of no sex at all due to her being pregnant with our twins. She and I agreed to have sex on either Friday night or Saturday morning every week unless it was "that time of the month" and in return I wouldn't approch her in a sexual way, or try to seduce her any other time of the week. That lasted two weeks then we missed two weeks (one was the wrong time of month). Then she went to every other week to once a month... to now it has only been once since 2004 started. I don't know how to get back to the agreement.
