I find there's definitely a link between total body release(orgasm) and headache. I'm Male btw. Sometimes if I already have a headache and orgasm(self or with a partner) CURES my headache, sometimes it makes it 10000% worse. Haven't figured out a pattern yet. Definitely a mental aspect to it, if I tell myself it'll get worse, it will.
food for thought: few years ago right after college I was living with my then girlfriend, all through my life till then I would get devastating headaches, only "cure" was to lie down away from people/noise/light. One particular night I got a headache, went to lie down away from everyone. She surprised me with fellatio, at first I resisted thinking it would get worse, but I relaxed, let it happen, and just like that I was cured. I felt as if I had slept deeply for 10 hours, was ready to take on the world. This happened two more times but never since. I wish I had the answer, it's there.
I've never been able to duplicate those 3 days, but know it's possible, hope this helps someone with headaches....
