Ok so my boyfriend has had a constant headache for bout 4 days now, no matter what he takes for it or what he does it dont go away. He jacks off at least once a day everyday(we are in a long distance relationship) but anyway when he cums his headache gets so bad that he cant stand it and is in so much pain why does this happen?
Simply because blood flowing from the brain is going into the penis so the blood pressure in the head is reduced therefore causing more headaches especially on the point of ejaculation. Try to get him to stop masturbating will ya?
If he has had a headache that long he should consult his doctor as that is not normal could be something simple but could also be life threatening so consult a doctor uegently.
