Have the two of you sat down and discussed this? There is a possibility that he has low testosterone. That was a problem in my last marriage. I couldn't even get him into the tub or shower with me. He let everything his mother told him stick. She told him that his mother told him a lady likes her privacy. All I could say was, "I'm not your mother, invade my privacy." Needless to say he didn't get it and things just got worse. That's when we ended up going to the doctor and found out about his low testosterone. That didn't help either because then he was depressed thinking he wasn't much of a man with a problem like that.
Talk it all out. There might be something that would help his drive. Maybe he feels like there is something missing and he needs that for more sex. There are endless possibilities.
They say the more men get it the less they want it. That comes from the fact that all of the sperm stored up have been released and it is taking the testosterone in his system to make more so he doesn't have the extra causing the urge to get it all out.
They also say that the more women are connected with their man and have sex, the more they want it. That comes from te fact that it was a pleasant experience and people always want plenty of whatever feels good to them.
So, it boils down to coming to an agreement on what will work for "both" of you. Whatever it takes to make you feel wanted by him as well as what it takes for him not to feel pushed into something he isn't up for.
Maybe, if the two of you are into oral sex, he could do you and skip a day for himself, going back to intercourse the following day. That wouldn't put as much of a drain on his drive from the hormonal standpoint and might work out well for the two of you.
Like Dr. Harley says, "brainstorm", come up with ideas to help alleviate the problem and make things good for the two of you together.
Good Luck!!
