I'm a healthy fit 51 yr old in a sexless marriage. We have a great business relationship and I don't want that to end but romanticly she no longer has any interest in me. What's a man to do? I'm tired of fantisizing and feel very frustrated. She says our lovemaking days are over , although we still enjoy dinners, family, mutual friends etc. It's easy to see why people have had secret lovers down thru history. That's the only route I can see for myself. But it's not easy finding the perfect mistress either. And I can't get excited about prostutes. I feel trapped.
