When this mom is questioning her own behavior, she asks Reddit:
My son (16 turning 17) had friends over going over the plan for his birthday, I rented rooms at resort for skiing and snowboarding for a 3 day weekend. They started talking about all sorts of things though, and eventually the topic of my son's sexuality came up.
My son is bisexual and has dated both girls and boys, he's currently dating a boy. Neither me or our family have an issue with this.
They're asking him when he realized he was bisexual, when did he come out, when did he first date a guy, what were the differences between guys and girls etc.
Eventually they ask him what's his preference, he says “naturally, I don't have a preference. I'm attracted to guys and girls the same, but after dating girls and guys, I can say women aren't worth the trouble.”
