While it may be far too late in this discussion for this comment to matter, I’d like to insert a single data point to the otherwise rampant speculation:
I was born into a crazy-hippie-gay/bi/straight-polyamorous commune. It was clear to me from as long ago as I can remember that many of my parents were fucking each other in various combinations, as well as sleeping with other people outside of the commune. Sex was always portrayed as positive, loving, fun behavior which healthy adults engage in but which is no business of children. I’m not sure how I “found out” that my parents were poly, since I never requested or was given details (no, I was not in a “sexualized” environment). I do know that however I figured it out, it was such a non-tramatic event that I have no recollection of it.
I was introduced to people of emotional import to my parents - long term lovers, friends, whatever. I’m assuming they had short-term affairs that I’ve never known or cared about. I’ve never been ashamed of their behaviors. I was brought up to beleive that sex is FUN, and anyone who is ashamed of happy happy fun is a little bit odd. I did have one parent who was a “slut”, which in my lexicon was someone having indiscriminate sex, and he was regarded as unhealthy by myself and my other parents because his behavior was compulsive, not because it was sexual.
I was surrounded by people who loved me and I felt safe and secure. While I fully understood that my family was far outside the norm, I just thought that was damn cool. I made a game of putting down different parent’s names on any school form given to me (keep’em guessing!).
After the commune broke up, I was raised by a number of different parents, most importantly my real mother. She eventually married and formed a (as far as I know) monogamous relationship with my stepfather. Many years later, another woman tried to initiate a relationship with my stepfather. I do not know if he did, in fact, cheat on my mother, but he was definitely enjoying and encouraging her behavior. Even though my mother and stepfather have healed their relationship, I still hate that woman and I’m still angry with him for hurting and betraying my mother.
Parents who love and care for their children aren’t going to tramatise them much with sexual revelations. Sex lives just aren’t really very relevant. Betrayal and pain ARE relevant, but those can occur in any type of relationship.
Just my two cents.
