Sometimes when I jerk off, I get a terrible pounding headache right before I jizz. This only happens maybe 5% of the time, but when it does it's weird ... comes out of nowhere and feels like my head is going to explode. But then it's just like a normal headache, take some aspirin and it pretty much goes away.
Anyone else ever have this problem? Been going on for a few years ...

Edit: I've also had this happen ONCE during sex, but only once... even more strange.
