It sounds like the set up for a joke, but a medical journal has revealed how a man approached doctors after suffering blinding headaches every time he watched porn.
The 24-year-old software engineer from India experienced exploding pain across his whole forehead every time he tried to view a sex video over a period of two years.
The first twinges of discomfort would strike just five minutes after he started watching a film and would build to a climax within eight to 10 minutes.
The case in India was a more unusual form of 'primary headache associated with sexual activity'
Neurologists in New Delhi who treated the otherwise healthy single man were at first baffled because he had no history of headaches, no family history of migraines and had never received a head injury. Physical and neurological exams also came back normal.
They suggested his case was caused by changes in the pain-sensing nerves in the face and jaw, which became more sensitive during a 'heightened emotional state associated with viewing pornography.'
Surprisingly, sex-associated headaches are not as rare as you might think. One in 100 people will experience at least one at some point in their lives, with men worse affected.
