My son, who is 18 years old, had 5 friends over. They were playing basketball and I could see my wife paying a lot of attention to them. When I called my wife out on it she didn't deny it. She said I look at girls so whats wrong with her looking at some hot sweaty shirtless young men wearing in just shorts. She said it that way to try and annoy me. They took a break from playing and were hanging out in our backyard. My wife suggests we ask them if they wanted anything to drink. She went out back to ask them and was gone for awhile before she came back. When I asked what took her so long and made a remark about whether it was to check out hot sweaty shirtless young men she said I was partially correct. She told me to go out and have my own look. I told her I was wasn't interested in seeing shirtless young men. She insisted for me to at least take a quick little peek as it might answer why she took so long coming back in. I was curious why she said that and went out to see what she was taking about. All of them, including my son, were out there naked. They seemed so casual about it and I didn't know what to say or do so I said nothing. My wife returned with drinks for them and just smiled at me. We went back in and my wife joked about having our son invite his friends over more often.
