My wife and I are in our early 50s. My wife is looking prettier and sexier than she ever has. How do I let her understand that I want to take advantages of these days and enjoy our sex life together. We hardly have sex. She's just not into it. And if we do it's at night when she is not looking hot. I don't want to be selfish. But I want to take advantage of these remaining days of before we get older. How can I motivate her to have sex more and when she's looking great? I know if I go down on her it gets her in the mood. But she will only let me do that after I beg for weeks for sex. Am I selfish?
