Generally speaking (and most ideally), sex is a pleasurable experience. The idea is that both parties (or all parties, permitting you prefer a group) orgasm. This is obviously easier when it comes to the male sex organ, as women's bodies are far more complex and their orgasms are just as much mental as they are physical.
That being said, even when partner A&B manage to reach The Big O, things can go a little haywire afterward. By a little haywire, I mean absolutely f-cking bonkers. It's amazing that even something as terrific as sex can be riddled with a chaotic response—us humans just can't catch a break, huh?
According to The Daily Star these adverse reactions are what's called the peri-orgasmic phenomena. Side effects include—
Hallucinations—"Of the 50 women who claimed to experience “expanded sexual response” (hallucinations) nearly all of them noted a flying experience or a sensation of flight a study from Turkey revealed."
Crying—"Postcoital dysphoria can include tearfulness, melancholy feelings, depression, anxiety and agitation."
Weakness—"The sudden onset of weakness that occurs with orgasm is called orgasmolepsy."
Headache—"Primary sexual headaches are orgasm-induced and could be caused by the adrenaline rush that occurs during climax."
Sneezing—"The reason some people sneeze after an orgasm is because a part of the parasympathetic nervous system activated during climax which can cause sneezing."
Uh, I don't know about you guys, but I'm not entirely sure even the greatest sex is worth hallucinating over. I can pretty much tolerate the other 4 symptoms. Would it be weird AF to have a sneezing fit shortly after ejaculating, sure? But stranger things have happened in the bedroom, I'm sure. I mean, people are noting if not kinky as hell nowadays—a little sneezing ever hurt anyone.
