This is indeed a fascinating thread. I think it's because everybody in a kink lifestyle has at sometime questioned why they are the way they are.

Speaking from my own experience, I believe it to be a biological thing. I remember at a very young age being extremely "interested" in any TV shows that showed anybody tied up or restrained in any way. I couldn't take my eyes off Mr. Brady of the Brady Bunch stuck in the stocks... little knowing that it was because twenty-something years later I would be excited to have the same thing happen to me. This was LONG before puberty or any thoughts of anything sexual had crossed my mind.

I've read that gays statistically rarely have gay siblings. I think this would point towards a biological, rather than environmental cause. (I know that it is not the same thing, but there could be parallels).

Honetly, if I could choose my lot in life, I doubt that I would choose to be a sub male. I accept though, that that is what I am and I know deep inside that there is nothing I could do to change how I feel.

...my two cents.
