There are two types of sex headaches:

• A dull ache in the head and neck that intensifies as sexual excitement increases
• 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.

Any type of sexual activity that leads to orgasm can trigger sex headaches.

Abrupt-onset and slow-to-build sex headaches can be primary headache disorders not associated with any underlying condition. Sex headaches that come on suddenly are more likely to be associated with:

• A widening or bubble in the wall of an artery inside your head (intracranial aneurysm)
• An abnormal connection between arteries and veins in the brain (arteriovenous malformation) that bleeds into the spinal fluid-filled space in and around the brain
• Bleeding into the wall of an artery leading to the brain (dissection)
• Stroke
• Coronary artery disease
• Use of some medications, such as birth control pills
• Inflammation from certain infections

Sex headaches associated with loss of consciousness, vomiting, stiff neck, other neurological symptoms and severe pain lasting more than 24 hours are more likely to be due to an underlying cause.

Sex headaches can affect anyone. But risk factors for these headaches include:

• Being male. Men are more prone to having sex headaches.
• History of migraines. Being prone to migraines increases your risk of sex headaches.
