My boyfriend sits with his knees spread far apart. I find it embarrassing. How do I tell him he is too old to sit that way. He’s 22.

Try a bit of humor. Why not say something such as, “Are your pants uncomfortable? Are they too tight?”

Then when he asks why you’re asking, tell him you think he looks really uneasy with his legs splayed far apart. His testicles must feel crushed from all the pressure. He’ll listen to that. Habits are hard to break. You’ll have to play with him about this every time you see him in his man-spread — in order to help him break the habit.
