I think my mom knows. I don't know how the hell she found out though.
We were in Big Lots! one day and we passed by the books that were on sale. I LOVE reading so I had to stop and see if I wanted to buy any. There was a novel called Bound I think with a woman tied up on the front. Next thing I know my mom says, "Oh look, bondage! You should like that." Now I was shocked and I didn't know how she found out and my mom is by no means stupid. I do live with her during holidays so it is hard to hide things from her. I just looked at her and said. "I don't want to hear that from you." And walked away. I'm sort of jealous of her though because she has corsets....as in multiple ones. I have no clue what she does with them and I honestly do want to know.
But to be honest I think she might be into bondage just a little, or at least kinky sex. My cellphone died and she gave me her old blackberry. I saw pictures of her that sort of make me think of her differently. There are somethings you never want to see your mother...the person who birthed you....in and a fishnet bodysuit is one of them. But I digress. I shall NEVER tell her what I am up to.
My cousin however is another story. We tell each other everything. I told her when I found out that I was like this. I think she's okay with it but she's not really into men. She's kind of freaked out by them I think. And since she's a year younger than me and we do art together we tend to tell each other things we find out about sex. I think she's okay with me being into bdsm which I like. I'm happy that she accepts me like this.
