I have the perfect wife. She is beautiful inside and out, everyone we know loves her. But, I have been cheating repeatedly with other men. I always do it safely, but I know if she found out it would destroy her. We have children, and otherwise out marriage is great, but I cannot reach sexual fulfillment unless it's with a man. I'm awful, I know this is so wrong, but I know telling her would destroy her. I couldn't imagined spending my life with anyone else, 8 don't have any emotional pull towards men, it's entirely physical.
