A first-of-its-kind study found men also exhibited a condition called “post-coital dysphoria” (PCD) that has previously been observed in women.
Forty-one percent of the male participants experienced PCD in their lifetime and 20% reported it happened to them in the preceding four weeks.
Feelings reported by the survey’s subjects varied from "I don't want to be touched and want to be left alone" to "I feel unsatisfied, annoyed and very fidgety. Some talked about feeling “emotionless and empty”
The results of the study show that how men view sex is much more complex and varied than assumed previously.
This condition can interfere with the interactions of the couple following sex. The study's author stressed that the postcoital stage—“the resolution”—is very important for building the intimacy of the couple. Those that “engage in talking, kissing, and cuddling following sexual activity report greater sexual and relationship satisfaction.
Scientists theorize it may have to do with the “dopamine rebound effect” when dopamine levels are lower after the sexual rush.
