>>12788008leading up to a nut your animal brain has been filling up with hormones to trigger arousal to a point of climax, dopamine is dropped and you're high off the release of stress.
it's all about the chemical triggers carried out unconsciously, like in extreme focus or fight/flight releases cortisol, you have an endorphin rush that builds up to orgasm and a refractory period (triggered by climax)
its similar to the action potential response, including the nut shiver some people get, which is multiple retriggering at that moment (and the point that pseudoscientists try to put their sex yoga in place) until the equivalent repolarization occurs. in that refractory period, if put in simple terms, your animal brain is returning to normal arousal, which when it overshoots gives a longer period where arousal is essentially shut down, even below your normal state of mind/"hornyness."
comparative animal biology goes over the importance of these sorts of hormone cascades during times of stress or arousal.
