My long-term lover enjoys being slapped, choked, and generally degraded during sex. Doing these actions increases the amount of mating we indulge in. Through this effect, I too find myself conditioned to sexual arousal in these circumstances, noticeably increasing the extent of my tumescence.
There are plenty of other females out there who desire similar treatment. Perhaps humans are not so different to baboons in this regard?
It's almost too peak HN to be taken seriously.
