Coital Headaches or Brain hemorrhage?

About two weeks ago,my boyfriend drank far too many bourbon and cokes and woke up with a terrible headache (he said the worse headache he had ever experienced). So at first we were thinking hangover headache. That afternoon he masturbated and said he thought he was going to die. The headache subsided that night but every time since then when we have intercourse he gets a terrible headache. He tried push-ups a little over a week ago and the same thing happened. Now yesterday and today, He's masturbated and tried push-ups and neither gave him a headache but says he can feel it coming on when he bends over. He feels the pressure on the back of his head. He is 33 years old and in better physical condition than most. He had been a little stuffy a couple of weeks prior. We checked his blood pressure and everything was normal but at the time he was not physically straining.

Ever since I have started researching sex headaches, I have worried. Because we were sold that it was a brain hemorrhage and since I have found information on coital headaches. He's currently looking for a doctor in Birmingham,AL and going to go in for a CT and MRI.  Please Help
