has anyone ever felt like they were going to pass out after orgasming?

i was masturbating in the shower earlier (ladies if you dont have one of those shower heads thats connected to a hose thing so you can reach..uh..lower areas..i recomend you get one, theyre amazing) and after the big O i seriously thought i was gunna pass out..i was dizzy with a bit of a headache and my stomache actually hurt a little and i needed to sit down for a sec.

this has happend to me before while having sex too once. it reminds me of the movie Mr. Woodcock when they talk about "blacking out from sheer pleasure" so is this actually possible?

just wondering
