Where's Chef when you need him? Anyway, if he were here. He'd tell you all about texture. Now texture is important and the male body knows this. Yes, for a while smooth cum is fine; it coats the palate well and goes down easily. Now this is where the genius come in, the body asks itself chemically how many times that smooth, glossy semen has been "shot" in the past couple of weeks or months (depending on the circumstances) and if the subsequent reaction is
too many times. Then the body will automatically chunk that shit up. Just for the sake of the diner. It gives them something to chew on, something that is similar but different. A nice treat for your partner you might say. They should be thankful too by the way. But they usually aren't, ungrateful bastard! Don't they know what we've been through to make that? Of course not, you flinch, you heave, you vomit!! You disgust me!
Now if the body goes through all this trouble just for it to be sprayed inside a dirty white sock or out of a moving train window then all that hard work will have been undertaken for nothing. Unless of course the shot out of the window hits a passing car - then all is not lost. But if not then I'm afraid your body has used excess energy for absolutely nothing and that's energy you aren't going to get back . . . until it's ... er .... replaced by more, of course. :dunno:
Anyway, always remember these great words by one of the all time great philosophers:
