Philosophical fancies aside, the intricacies of the human heart are known most plainly to chemists.

We can spend years musing about the psychological precursor to our tastes or behavior, but can often learn as much in minutes from a scientific explanation. And while the full complexity of conscious experience is mysterious and unknown, there are clear links between certain chemicals and our most basic drives - explaining, for example, why we feel horny one moment and mellowed another, or why our sex drives are highest after exercise.
At the core of sexual pursuit are the yin and yang of lust, two vastly different substances but with complimentary roles of switching desire on and off: dopamine and prolactin. They regulate more than sex, but for our purposes we can summarize; dopamine plays a central role in generating horniness - while prolactin shuts it down.
Chances are you’re familiar with the effects of each. Dopamine, a neurotransmitter and relatively small molecule, is your brain’s sense of pleasure and reward. It fires when we see a pretty face, taste sugar, puff a cigarette, or touch skin-to-skin. When your dopamine levels are highest, sex is number one on the agenda, sometimes by so much that you’ll have lower-than-normal interest in food or sleep. (more…)
