That's the first time I've seen fit to use the word "post-coital" on this blog, though it did appear — once — in a quote:
"I realised one day, as I gazed out on the treetops outside the bedroom of our little cottage, that the usual post-coital rush of a sense of vitality infusing the world, of delight with myself and with all around me, and of creative energy rushing through everything alive, was no longer following the physical pleasure.... I felt I was losing somehow, what made me a woman, and that I could not face living in this condition for the rest of my life."Recognize the distinctive authorial voice? It's Naomi Wolf.
That post ends — aptly! — with this:
"Yes, a profound sense of fatigue, a feeling of emptiness followed [the physical act of love]. Luckily, I was able to interpret these feelings correctly."
Here's the Wikipedia article, "Post-coital tristesse":
Post-coital tristesse (PCT) or post-coital dysphoria (PCD) is the feeling in humans of melancholy, anxiety, agitation or aggression after sexual intercourse (coitus). Its name comes from New Latin postcoitalis and French tristesse, literally "sadness". Many people with PCT may exhibit strong feelings of anxiety lasting from five minutes to two hours after coitus.We'll see how Trump and Pence do.
The phenomenon is traced to the [ancient] Greek doctor Galen, who wrote, "Every animal is sad after coitus except the human female and the rooster." The philosopher Baruch Spinoza in his Tractatus de Intellectus Emendatione writes "For as far as sensual pleasure is concerned, the mind is so caught up in it, as if at peace in a [true] good, that it is quite prevented from thinking of anything else. But after the enjoyment of sensual pleasure is past, the greatest sadness follows. If this does not completely engross, still it thoroughly confuses and dulls the mind."...
