Hmmm interesting question. I too only let my submissive side come out when I turned 40and am amazed that girls as young as 18 know what they do about BDSM. I know I had no idea at all it even existed at that age!

I was lucky to meet two special men, both who just happened to be older then me. I didn't set out to get to know either of them, but it just felt right.

Obviously some Doms do prefer younger girls, just like some vanilla guys prefer younger girls. Lucikly for us, all Doms are different and there are many who prefer girls that are not 18!
