Youngblood, I would have to agree with the last post. "Finding" a D/s relationship with an on-line search is no different from finding a vanilla one. No wonder you see a skewed view of dominant females.
I've had two fulfilling relationships in which my partners discovered their dominant sides with me and that side of the relationship subsequently flourished. IMO I think it's like anything else intimate... once you have found compatibility with someone on the more casual levels, you explore it and if it doesn't work, then you move on.
Trying to do it the other way around would be like a vanilla walking into a bar and starting conversations with strangers about their fave sexual positions... then buying them a drink if they agreed. (that might sound a little far out, but I think the comparison works)
