There's a lot of fantasies without that much root in the real world in the story part of this site.
The forum though is a great source for info. I would also recommend fetlife.com "the facebook of kink".
Anyway, being a sub isn't about not having a choice at all in what happens.
You choose what you want to be involved in and what you're open to trying out.
The whole point of the dom/sub stuff the way I see it is to realize our own fantasies and enjoy ourself, our kinks and our fellow kinksters while helping them to experience and enjoy theirs.
And like Kurius, I sort of envy you that experience in that party :-Þ
Before now I've lived in places without a community and now that I do have one nearby I simply don't have the time due to studying nor the courage to approach them ><
