I have been married for over 10 years…together for 18.
If you truly are interested in sex once a week and he 2-3 times then the gap you have to bridge may not be all that significant. The real issue is can he manage to live with 1-2 a week and conversly can you live with 1-2 as opposed to just once?
"Of course once a week is more than she genuinely wants. Why would she want any sex with this person, who obviously has some issues when he doesn't get what he wants?"
When you see it coming, duck!
For many years, if I was not in the mood for sex when he was he would get angry and upset with me, storm out of bed and not talk to me or pout for several days afterwards.
In the beginning I would definitely say I was a once a week'er for sure..where I would feel in the mood, but as time went by and the anger came out of him for what he felt as being rejected I got wore out with it.
