I was ready to the call the doctor about it when my son confided to his father that he gets these headaches only when he masturbates. My husband says he thinks he can recall having similar headaches when he was young. Have your readers had similar experiences? I am still worried, but I realize the embarrassing situation my son is in and don't want to rush to the doctor if it is normal.
I have heard of this before in several places, and I've also heard a medical doctor say it's probably nothing to worry about, unless there are other symptoms (dizziness, blackouts, etc.), or if the headaches sometimes hit suddenly and unprovoked. He is probably just sensitive to the high blood-pressure levels that occur when he's sexually very aroused. But if the condition persists and it's enough of a problem that it's adversely affecting his quality of life, I'd have him visit the doctor.
