Rowan is a pretty good leg rider (in my totally unbiased opinion.) She got good at it because her male coaches had no compunction teaching the techniques or demonstrating them on her.

I find it kind of funny when folks get all weirded out by some wrestling positions when its a male and a female but they have no problem when it is a couple of guys. The deal isn't the positions, it is the context. As long as you keep the context about wrestling, there should be no problem.
