So if a man suddenly changes his mind, mid-penetration, is he a victim of rape too?
If both man and woman change their minds at the same time, are both considered rapists?
How intriguing.
Philosophically, the partner performing the penetration has a bigger responsibility. So if you are a man penetrated by a woman and you want to stop mid penetration then she has to stop, if you are the one penetrating just stop yourself.
