I don't really know what to tell you. I mean honestly, you should have made a stern decision years ago. I know sex isn't everything, but to a lot of men, its very important. To stumble through, and jump through hoops, go long periods of time without, just for regular vanilla sex. That just isn't fair to you. Its like she's rationing her p---y to you, or using it as a weapon to control you. As far as my religion has taught me, we have 1 life on this planet. And when you make the committment to spend the rest of your life with a woman, you cheerish her, love and respect her. The least she can do is make love to you a couple times a week. I realize our bodies go through change, physically and emotionally. BUt sometimes, certain situations aren't fair.
This is one of them.
