Dear Prudie,
I am a male college student, and ever since I can remember, I have spent a week or two visiting my aunt, uncle, and cousins during the summer. One of the cousins is a few years younger than I am, and I have always thought of him as a brother. I was there on vacation last week. One day while my aunt and uncle were at work, I walked in on my cousin masturbating. He had a necktie attached to his bed post and wrapped around his neck, and was performing something called autoerotic asphyxiation. I quickly left the room, and we didn't speak a word about it. I know that for his own good and safety, I probably should tell his parents, but I don't want to ruin our great relationship by divulging something that is very personal and private. I would love to tell them anonymously, but they would know the information was from me. I remember the time I got caught doing the deed by my parents (I, however, was not choking myself) and how horrendously embarrassing it was, so I don't want to unnecessarily humiliate him. What should I do?
