Freaky people who know what they're talking about: help me!

Ok, so I have strong sub tendencies and have had them since puberty. I'm a pretty normal person, don't have any traumas that would affect me that way, and I'm a generally self respecting feminist. I was disturbed by this and wondered whether I was crazy or not. About a year ago, I asked two online collumns (I know) about this, and got two variations on 'you might be unconventional, but you have nothing to worry about'. From there, I decided to research throughly. I've read pretty much everything I could find on the internet (choosing wisely of course), and I think understand and accept kink in general.
