“The role of dominance and submission in human sexuality cannot be overstated. Our survey suggests that the majority (over 50%) of humans are very aroused by either acting out or witnessing dominance or submission. But it gets crazier than that: While 45% of women taking our survey said they found the naked male form to be very arousing and 48% said they found the sight of a penis to very arousing, a heftier 53% said they found their partner acting dominant in a sexual context to be very arousing. Dominance is literally more likely to be very arousing to the average female than naked men or penises. To say: “Dominance and submission are tied to human arousal patterns” is more of an understatement than saying: “Penises are tied to human arousal patterns.”

We have a delectable theory about what is going on here: If you look at all the emotional states that frequently get tied to arousal pathways, the vast majority of them seem to be proxies for behaviors that would have been associated with our pre-human ancestors’ and early humans’ dominance and submission displays. For example, things like humiliation, being taken advantage of, chains, being used, being useful, being constrained, a lack of freedom, being prey, and a lack of free will may all have been concepts and emotions important in early human submission displays.

We posit that most of the time when a human is turned on by a strange emotional concept—being bound for instance—their brain is just using that concept as a proxy for a pre-human submission display and lighting up the neural pathways associated with it, creating a situation in which it looks like a large number of random emotional states are turning humans on, when in reality they all boil down to just a fuzzy outline of dominance and submission. Heck, speaking of binding as a submission display, there were similar ritualized submission displays in the early middle ages, in which a vassal would present their hands clasped in front of their lord and allow the lord to hold their clasped hands in a way that rendered them unable to unclasp them (this submission display to one’s lord is where the symbolism of the Christian kneeling and hands together during prayer ritual comes from). We suspect the concept of binding and defenselessness have played important roles in human submission displays well into pre-history. Should all this be the case, why on earth have our brains been hardwired to bind (hehe) our recognition of dominance and submission displays to our sexual arousal systems?!?”
