Hi Ross and welcome ot the forum. You can't help finding out this is a very open-hearted and friendly place, animated by respect and interest for each other and our kinks, most of all a respect for whom we are. I'm sure you'll find subs, slaves and Dominants who are willing to talk about their roles and why they are into this, and as one of the few openly trans submissives of this place, I'm directing you right away to the thread I posted two days ago called Louise bares it all (on the "My BDSM life" forum). It's both about my personal views on subbing and why i chose to unequivocally take the female sub role although I'm not, well, natural for it.
Warm welcome!
