Dear Prudence,
My sister used to be a professional dominatrix. She was quite open with me about this and said that she stopped because she was tired of being “topped from the bottom”; she wanted “real” control. We haven’t discussed this for some years now, and it never occurred to me that it might not be a good idea to leave my preteen son alone with her. The other day, I arrived early to pick him up, and it took my sister a while to answer the door. It appeared that she and my son may have both hastily put their clothes back on. I later asked my son what happened in general terms, so as not to sound accusing of anyone. His answer was plausible, but it almost sounded rehearsed. I’m not sure what to do. Maybe nothing untoward happened and I’m just being paranoid. I love my sister, and I really think she would know better than to do anything remotely sexual with her nephew or anyone his age. Should I talk to my sister and hope she can assure me that everything’s OK? Or should I just assume the worst and never again leave my son in her care?
