you should see a doc as it could be more serious and needs to be checked out , not wanting to scare you but it is a common syptom of an aneurysm ! or could be as simple as high blood pressure but does need to assessed by a doc . x x
I'd wager that you are exerting yourself very hard during sex - harder than your physical work.
Sounds like the pain is coming from your sinus - you could have a bad sinus infection. Have you had a bad cold recently?
You should see your doctor. It's more than likely nothing, but there are other things it could be that are serious.

I dont really exercise . But I work alot physicaly and never get head aches.Only during sex does this occur.
Drz;
Do you have the same headache whenever you are exerting yourself with other exercise? Or is it only during sex?
