in my research, and my vast knowledge of what I learned in history class, I've found this:
4. Can urine be ejaculated instead of semen during sexual intercourse?
No. When the penis is erect, there is a built-in valve which switches the plumbing from “urine eject” into “sperm eject”. The same mechanism that prevents urination during erection also prevents erection during urination. That is why it is difficult to urinate during an erection and, conversely, why an erection is lost during urination.
I've searched sooo many times for this video for responses such as this, but has anybody seen the SNL skit where Alec Baldwin is in the "burn and Zing" battle and he goes "Oh, can you hold my coffee?" and then the dude holds the coffee and then he asks him what time it is and the dude holding the coffee turns his hand to check his watch and spills the coffee all over him, burning him and then alec baldwin goes "BURNNNNN"!
