with regards to getting men to be rougher with me, I usually find the good old, "oh yes right there, harder, there HARDER HARDERHARDER fuck me, I like that" works a treat.
Rougher sex can just be thrusting harder, or holding her hands over her head/ behind her back. A lot of the point about being dominant is that you have to have much more self control, be concisive, and exact, rather than letting yourself go.I believe a lot of doms preplan their sessions to help them stay in control.
I can understand where you're coming from with not wanting to allow yourself in to that dark space tho. I am generally a very controlled person in the bedroom with someone who I dont think can be dominant with me because when I let go I have caused serious damage, bitten and scratched hard enough to draw blood, sent men flying across the room kicking them off the bed etc. and I've not even remembered doing it so I am careful that side of me only comes out with either a man whos strong enoughto restrain me if needed, or a man who enjoys that side of me, or both.
I did find someone to allow that this week though and it was amazing
