Neither of my parents knows anything about my sex life, other than I have sex. I figure it works both ways - I don't want or need to know about their sex life, and vice versa.

If they hypothetically found out... my father wouldn't give a sh!t. He's always been very much the "do whatever you want" sort of parent, incredibly accepting and permissive. I can picture him asking a few questions about it, like how many people I've played with, how long I've been doing it - basic stuff. My mother would flip out, and I'd have to explain in gentle and thorough detail that her precious daughter is doing this stuff voluntarily and safely. And then I'd have a stiff drink. She accepts that I'm my own person and lead my own life, but that doesn't stop her from being shocked at what she perceives as my "out there" choices - like being tattooed and pierced. (Hooooo boy, the tattoo conversation was a tough one!)

My best friend knows, and she's even more into the scene than I am, so she's totally accepting and encouraging. Another friend knows because we're open about our kinks with each other - I don't think he quite 'gets' it, but then I don't 'get' his anal sex kink, so there you go. My ex-roommate knows because he saw the ropes. As far as I'm aware, that's it.
