I first spanked someone, sexually, when I was 18.
I can't actually tell you why. She was my girlfriend. I loved her, as much as you are capable of loving when you are 18.
I hadn't yet read the Story of O. I didn't know anything about feminism, or the possibility that spanking someone, or dominating them, might mean something...
I've started a blog
here for those who aren't members of this sexy community - I'll crosspost any original writings...
