I'm a gay man who is ready to start cheating on my boyfriend. We've had a wonderful 3.5-year-long relationship full of respect, affection, support, and fun. I love everything about our relationship, and our sex life was great. . . until he moved in eight months into the relationship. At that point, he lost all interest. I've tried everything: asking what I can do differently, being more aggressive, being more passive, suggesting couples therapy, getting angry, crying, and breaking up twice. (Both breakups lasted only a few hours because I honestly don't want to leave him.) When I bring up an open relationship, he just goes quiet. I've moved past most of the anger, frustration, hurt, embarrassment, and sadness. But I won't accept a life of celibacy. I would like to get some discreet play on the side. My boyfriend is very perceptive, and I'm a bad liar. I don't want to get caught—but how should the conversation go if (when) I do? I'm leaning toward something like this: "I'm sorry it came to this and I know we agreed on monogamy, and I gave you monogamy for 3.5 years, but part of agreeing to monogamy is the implicit promise to meet your partner's sexual needs. Everything else about our relationship is wonderful, but we couldn't fix this one thing, so instead of continuing to push the issue, this is what I decided to do." Good enough?
