Why do men pee in these crazy urine streams after having sex?
In: Biology
Just a quick reminder that males have a spongy urethra and this particular structure creates a spiral urine stream which expels urine at higher speeds and this functions as a way to remove obstruction, like sperm in this case. Females do not have this structure and why there’s a higher incidences of UTI’s for females vs. males.
After sex, you have a combination of foreign objects there such as:
* sperm
* lubrication
* vaginal fluids
* spermicide
Which clogs up the very tip and, in the case of sperm, parts of the shaft.
This is why it’s always good for men (and women) to pee (and wash off) after sex because it cleans, well, everything.
The same streams can happen at any time throughout the day but for similar reasons: basic blockage in the tunnel, so to speak.
Pro-tip for your pro tip: break the blockage before urinating by spreading open the opening of the urethra.
The most likely culprit is drop of semen. It can dry and glue parts of the opening distorting the flow.
The guys starts peeing expecting it to flow straight like always, and instead shoots off in a weird direction.
The crazy urine streams are caused by semen that has dried at the exit of the urethra. After a short while, the urine dissolves or dislodges the plug and the stream returns to normal
I’ve got a tattoo here that fully illustrates…. It’s of this rebellious young man, and he’s urinating on an FM radio. And then this other stream of urine is going onto that television set. Implausible, I know, but I like to think that he had sex the night before, and a little bit of residue is blocking his urethra, allowing the urine to flow in two separate directions
Aside from the obstructions mentioned by others, also attempting to pee with erection or after a prolonged erection can cause this just because the head is engorged with blood, thus changing the overall shape of the opening. A bit like lightly squeezing the end of a straw while trying to spray water through it. The water isn’t prevented from coming out, but it definitely comes out in a significantly different spread!
