Sex headaches?

Autum
I don't know if this is something normal to experience but for about the past two years after I have intercourse (with orgasm) I get these crippling sharp pained headaches to the point where I've just decided to stay laying down for a minimum 5 minutes after. I cannot even lift my head up or the pain is just unbearable. I've always been too embarrassed to ask my obgyn and I was going to at my last visit and forgot because of all the baby talk we had going on. I googled it and it just scared me. So I won't be doing that again. Just wondering if any of you ladies are familiar or have also experienced this sort of thing?
