So, I Fainted...

Scene: My husband and I are enjoying the perks of matrimony in a doggy-esque position. About 4 minutes in I start tapping the bed like a crazy person; I guess I forgot this wasn't an actual wrestling match. Why am I tapping out? Because I'm dying. Not the omg, this is it, sad kind of dying, but the holy crap this feels so good...almost too good...way too good. I can't take this level of pleasure but I'm about to cum to f*#$ I can't breathe kind of dying. And then it happpened...bright lights to no light. About 5 or 6 minutes later, I don't really know when, my face hurts...like really stings. Then I feel a slap. My husband is slapping me, wtf! Not terribly hard but I can see the panic in his face. He says that I screamed and then stopped moving and he seriously thought I'd had a heart attack or something and was considering calling 911 because although I was breathing I wasn't responsive.

Is this something I should call my doctor about or is this relatively normal? Have any of you passed out during orgasm? I'm asking for a friend 😝
