We don’t think too much about sex; 
we’re merely thinking about it in the wrong way.

"(...)
Despite our best efforts to clean it of its peculiarities, sex will never be either simple or nice in the ways we might like it to be. It is not fundamentally democratic or kind; it is bound up with cruelty, transgression and the desire for subjugation and humiliation. It refuses to sit neatly on top of love, as it should. Tame it though we may try, sex has a recurring tendency to wreak havoc across our lives: it leads us to destroy our relationships, threatens our productivity and compels us to stay up too late in nightclubs talking to people whom we don’t like but whose exposed midriffs we nevertheless strongly wish to touch. Sex remains in absurd, and perhaps irreconcilable, conflict with some of our highest commitments and values. Unsurprisingly, we have no option but to repress its demands most of the time. We should accept sex as inherently rather weird instead of blaming ourselves for not responding in more normal ways to its confusing impulses.
(...)
Without sex, we would be dangerously invulnerable. We might believe we were not ridiculous. We wouldn’t know rejection and humiliation so intimately. We could age respectably, get used to our privileges and think we understood what was going on. We might disappear into numbers and words alone. It is sex that creates a necessary havoc in the ordinary hierarchies of power, status, money and intelligence.
