Dear Abby: I am the single dad of two teenage boys (17 and 18) who are both in high school. I am wondering about something they do with their friends. The boys take showers in large groups. When they come in from running or sports, or if a group is spending the night, they shower in groups of two, three or four. It's not like we have a huge shower ­ it's normal size.

I know there's nothing sexual going on because I can hear them talking and joking around. When I asked the boys about this, they looked at me like I had two heads. They said it was just a social thing and the same as showering together after football in the school gym.

They also "air dry" after showers by walking around in towels, sometimes watching TV or goofing off for hours while in their towels. When going out, they get naked in the bathroom, fixing their hair, shaving, brushing their teeth, etc. It's like a big "nude fest" with them and their friends.
