I had a friend who worked on a medical team at a hospital where military people and their families went to receive the care they needed. He told me that one day a married couple that he knew was brought into the Emergency Room because of a very embarrassing situation they were in. They had gotten stuck together during a certain sex act and position they had tried out. The wife kept telling her husband, "I told you it wasn't going to fit!" as they were being taken into the Operating Room.
Because of their condition, they had to end up having surgery to get unstuck from each other. My friend said that he was trying so hard not to laugh at what he was seeing when they were brought into the hospital. I told him that I wouldn't be surprised if that couple had eventually gotten a divorce after all of their disagreements, as well as after this humiliating episode. But he said that they were still together. I'm sure that they most likely won't be trying that sexual position anymore though.
