A post-coital stroke can sometimes occur after vigorous lovin'.
By now, I'm sure you've heard the tale of the English nanny who, essentially, whacked off to death. No? OK, sordid story short, a 30-year-old woman from Merry Olde England suffered some sort of arrhythmic disaster likely brought on by exposure to pornography and use of a vibrating sexual aid. More or less, she was found with said device and her computer open to the kind of content that male comedians always worry about being found with were they to die very unexpectedly. Sad indeed-y.
At any rate, death from exertion / over-stimulation isn't common, but it isn't as uncommon as you might think. Per The Daily Beast, roughhousing in the boudoir can lead to a thing called VAD (vertebral artery dissection). Essentially, a small tear occurs in the vertebral artery near the neck and leads to a clot. Generally, VAD happens during other strenuous activities, but rough sex can cause the malady characterized by numbness, palsy, headaches, vision loss and dizziness. The Emotional Side Of Rough Sex
While strokes are generally thought of as an older person's problem, VAD occurs mostly in youngsters (people in their 20s and 30s). Obviously, most guys will feel a small amount of pride in sexing a young woman until she can't feel her legs or at least until her face is beet red (what? I thought this was the trust zone and the tree of truth), but any of the above symptoms should be taken seriously; maybe not as serious as a heart attack, but certainly twice as serious as angina. So maybe you won't think the song "Strokin'" is so funny next time, but you can still enjoy Billy Squier's "The Stroke" and feel so-so about the band The Strokes. Woman Suffers Post-Coital Stroke
Be careful out there and see a doctor if any problems persist. Tylenol for fevers, Advil for headaches, Midol for cramps and baby Aspirin to stave off heart issues.
