It afflicted me first on an afternoon as my girlfriend was generouslty fellating me 'all the way'. As I approached the point of no return I suddenly felt a pain shoot up the back of my head and consume my entire cranium a second later. I pushed my girlfriend away and asked her simply to 'leave' and I rationally felt that I must be having a brain haemorrhage and rolled off the bed in pain expecting, in all likelihood, to die with no realistic prospect of successful medical intervention. As it turned out she remained and said 'what have I done' and after a couple of minutes of writhing about I told her it wasn't her fault but that my head throbbed and I needed to sleep. A few hours later the head pains and neck tension released and I was back to normal .
After a repetition a couple of days later ( although without the expectation of death) I visited my doctor and he pronounced that I was the only the second case of occipital cephalgia brought on by sex he had seen in 33 years. Being an asian (Indian I believe) he wrote it down to avoid misunderstanding and he told me not to worrry it would go in a fortnight. Well, it did, but it took me a good few months before I could really let myself go during sex because every time I neared orgasm and felt that 'welling up' sensation I feared the all-consuming head pains (like a gas cannister has been released in the back of your brain followed by an hour and a half of a blue whales heart doing your blood pumping whilst you nurse a hangover) that dogged me previously.

I wonder if anybody else has experienced this or if I'm the only one on these boards??
