Our expert says:
Sex-related headaches (coital headaches) do occur and tend to affect men more frequently than women. The cause is still unknown. The severe headache starts very suddenly just before orgasm and can remain for 10 - 15 minutes then gradually lessens. See a more detailed explanation for this condition in Health 24 - Headaches and Migraines (under medical conditions). Firstly, it is very important to have a thorough check-up to make sure the headaches are not related to some other underlying disease. After that, suggestions from the Health 24 article include waiting for a couple weeks before having intercourse again, then starting by trying different positions and perhaps a more passive approach to reduce sexual exertion. Please get this checked immediately especially if it has started suddenly.
