My first BDSM instincts were appeared in my childhood. In primary school there was a girl that I adored. She was so cute and pretty that much she was honouring my dreams However the dream scenarios were based on bondage. In the common scene, my girl was disciplined by her mum and was hogtied to a chair. She was, completely helpless, begging me to untie her.
So my first meet with BDSM goes far back. I hope you assume this dreamings as a primary experience, do you?

Actually, I cant say I had a "real" BDSM session before but I at least know the ways to get what I want I am a bastinado lover and with my friends I try to talk about it and try to apply it (of course lightly) as much as I can.

My first BDSM experience, was with someone that was probably the best lover of my life. I found the sex getting rough, and finally had my first orgasm during the rough sex. I was able to take that and expand it and explore it thru time. Since that time, i have found that sex without the pain, is boring and very mundane. 😉
