Rape is the core of male sexuality, for two simple reasons.
Another way to modulate the rape instinct is for men to express less-extreme forms of sexual dominance in order to compensate for the lack of freedom to breed at will. For some men, it can be as simple as being on top. For many, facial ejaculation or requiring semen swallowing seems to be a standard gesture of masculine power. Other men need to humiliate their partners in various ways, or demand public tribute, perhaps in the form of oral service in the corner of a bar. Rough sex, including pain-fucking, choking, gagging, and slapping, is a further step that some might find they need to take.
In my experience, the most exciting sex involves the free expression of this fundamental and violent aspect of male sexuality, to an extreme that stops just short of real rape. A violation of consent must never occur. At the same time, the man should feel just about as powerful and triumphant as he would have had he really forced himself into a unwilling victim.
Male sexual supremacy isn't inherently destructive. On the contrary, it must be simultaneously encouraged and controlled. In a state of equilibrium with the will of the penetrated subordinate, it is a glory like no other.
