Guys and cunnilingus

I've never seen the logic of spitting a mans ejaculate. If he shoots at the back of your mouth and you let it roll right down your throat, little or nothing will hit your taste buds. But if you are attempting to spit it out more will go over your tongue, mix with your saliva, and stick to parts of your mouth. This would result it tasting more, not less. Not wanting it shot in your mouth in the first place i get, but spitting makes no sense.

I would think with a vagina it is completely different because it is directly on the tongue and throughout the entire experience, so spitting or anything else, seems futile to me. But I have no experience with it so I can't say for sure.
