Sex headaches are brought on by sexual activity — especially an orgasm. You may notice a dull ache in your head and neck that builds up as sexual excitement increases. Or, more commonly, you may experience a sudden, severe headache just before or during orgasm.
Most sex headaches are nothing to worry about. But some can be a sign of something serious, such as problems with the blood vessels that feed your brain.
There are two types of sex headaches:
1. A dull ache in the head and neck that intensifies as sexual excitement increases
2. A sudden, severe, throbbing headache that occurs just before or at the moment of orgasm
In some people, both types of headaches are combined.
Most sex headaches last at least several minutes. Others may linger for hours or even two to three days.
Many people who have sex headaches will experience them in clusters over a few months, and then they may go for a year or more without having any sex headaches. Up to half of all people with sex, headaches experience them over the course of about six months. Some people may only have one attack during their lives.
