Over two years, every time a 24 year old bachelor who lived in India watched pornography he experienced such a severe headache that it forced him to stop watching.
Dr. Amy Gelfand, a neurologist at the University of California, San Francisco School of Medicine, says that there are two types of headaches associated with sexual activity.
Sex headaches are a mystery regardless of the type and no one really knows what causes them, says Gelfand.
There are no suggested links between headaches and specific sexual behaviors that have been found in studies by researchers.
The physical and neurological exam results were reportedly normal.
The man was advised to take a combination of different medications which, apparently, are helping.
