Wow! Great suggestion there Hella!
I "top from the bottom" in my play too. Didn't really know that it was considered as a term. I suppose if you are pro-domination then you would probably not like being made to punish but should be up to you when to punish. As for the proffesionals, well, sods to them! Lol!
Power struggling (another thing I didn't really know there was a term for) is something me and my partner do on a regular basis! We wrestle and he locks me in holds and I try to get out of them. I've always liked that since I became sexually active, having lots of male friends meant a lot of horse-play went on, but later I discovered that I was particularly enjoying it. :-/
Holds, locks and pins are great to try and calculate how to get out of them. Arm locks and such and knowing where pressure points are is simple if you want to reverse the tables, and size and strength has nothing to do with the ability to lock your partner.
What Hella said above about it being a good workout, fun and pumping endorphins is really true!
Unfortunately for me, my man knows every trick in the book to prevent me from getting out of his holds! But it is fun to be literally helpless and vulnerable! Just annoying when I really do want to get out of it! Lol!
