Began with a fetish for masks and black clothes when I was thirteen. Went over to dreams of bondage with 20, and found BDSM with 28.

I find a lot of possible reasons in my childhood (family was good, but all the rest...). Today only one thing is important: it is part of myself, nobody can change it, and I like to be as I am.

My opinion of what the reasons are: human beings have the instinct to play. Playing helps to learn, to prepare for difficult dangerous situations. SM-people play the things they fear (or have once feared) most. Together with sexuality, it becomes addictive.

Note: that is only a theory, completely grown on my own rubbish, so nobody else is responsible for it.
