i thought i would add my experience to the collection...  I am 21 years old, male, i remember getting a handful of orgasm headaches about 3 years ago   and they mysteriously vanished after a week or two.  Last week i was running, i was pushing myself harder than usual and all of a sudden got a throbbing headache in the center of my head that felt like it was pulsating from the center of my head out to the sides. It seems to be in rythmn with my heart beat.  it lasted for about an hour and slowly disapated. The next night, after i had ran the day before, i experience that same headache at the moment of orgasm and it lasted for about an hour as well. I don't typically get head aches, and I wasn't exerting myself like when i was running, i was rather relaxed, i was receiving some enjoyable oral sex until it ended in a throbbing head ache. So im convinced that its the very act of orgasm that has given me the headaches, because its happened the last three times even when i had very low levels of physical activity.

am i a rare case being so young and  experiencing this?  and i also saw that this is something typically experienced by females? any thoughts there? could i have injured blood vessels in my brain when i was running?  i have been experiencing minor head aches hear and there, outside of the sexaches, ever since i ran.  I have rarely experienced headaches before this.
they are very uncomfortable but they are not as painful as i remember when i had them three years ago.  So this makes me feel like they will probably go away but i have no idea if this is something i should take more seriously.
