OP, I am. I've been submissive since I first discovered my sexuality (age 8), so it's perfectly natural for me. I hadn't experienced anything traumatizing or uncomfortable at that age - I feel as if I was born this way.

And I don't agree with the psychological stigmas around it. I'm a pretty dominant person by nature, and thats why I enjoy being dominated in bed - and the same goes for a lot of BDSM / D/S people.

And yeah, there are healthy ways to explore it and there are unhealthy ways. We have two mottos:
SSC = Safe, sane and consensual
RACK = Risk-Aware Consensual Kink

We use safewords, for example "red" means full stop and "pink" means "it's a bit too painful/I don't like it/Please don't do that" - or whatever safewords you want.
It's roleplay, though some people live in 24/7 D/S relationships - that's a bit too much for me.

A lot people who are coming out of the BDSM-closet late in life feel guilty, abnormal, ashamed etc - similar to homosexuals who discover their preference late in life. And BDSM is still on the list of mental disorders and parafilias - which homosexuality was removed from years ago.
There are different reasons for why someone enjoys BDSM, and I can say - if it's because of traumas, or a way to vent anger, or a way to punish yourself - you need psychiatric help, cos that's not healthy.

Feel free to PM me about this. There are lots of forums out there for people who are intrigued by it.
