PHYSICAL strength means dominance! A dick or being on bottom means nothing. So a woman stacked with 300 pounds of muscle hard as frozen steel on bottom, and a 140 pound male on top...Think hes dominant because hes on top? Think about it. The ability to pick someone up and fold them 5 ways makes them dominant...not sexual position.
The largest and most powerful animal is the alpha...same with humans. Carefully evaluate a long term crowd of people. The largest and strongest always naturally assume the leader role, its how we are created. Your silver tongue will not stop one who's stronger and bent on harming you.

So one is a lanky trained black belt. Okay, they can fight...but contemplate the damage they could do if their body is conditioned for power. This is why they dont pit people together with the same skill level and dramatic size difference. Why? Because the larger one will destroy the smaller.
It continues to urk me hearing people say the bottom is not the alpha, even though in a fight for dominance, the one who happens to be relaxing on their back will leave the little spitfuck in a pile of bloody paste.

Another thing. Muscle is muscle, it doesnt matter what gender its on...you work it, it will grow. Im living proof of this.
