Courting Disaster, my weekly comic about sex, love, and relationships updates every Friday. You'll laugh your pants off. This week's question:
While at a friend's party, my wife and I were introduced to another couple (we'll call them Joe and Diane) who were close friends of the host. I went to circulate, leaving my wife with Joe. When I returned, they were sitting cozily together, and when I looked at her face I knew they had made love. She denied it. What should I do?
