It would appear that you are masturbating in the restroom. This is not particularly dangerous although it might be embarrassing if it is a public restroom. I would recommend doing that at home in your bedroom instead.
i don,t think sperm comes out after one hour. sure not with urine
If there is sperm or semen left in the penis or the vagina after sex it can wash out later with your urine. This is no problem at all and perfectly natural.
this is a one way exit. its where sperm and excretion comes out.
Sperm can't come out through urine. Even if it could, you wouldn't be able to catch it from a toilet.
No. Urine comes out of a different, valve if you will. This valve is connected to your urethra which is directly above your vagina. Therefore, the sperm in your vagina really has no contact with your urine as it leaves your body.
During sex, sperm goes in the vagina. Urine comes out of the urethra. These tubes are not connected, so a woman does not "pee sperm out" in any circumstance.
Penis...The Penis is where fluids are emitted from the male body. Sperm, Semen and Urine all pass through the Penis. And if it comes out your mouth that means when you was young and if your mom kissed you, you would of gave sperm's to your mom.( witch is not true).
It keeps urine from being released until you use the restroom.
They can. Their restroom may be broken, dirty or occupied.
urine
no
Urine is acidic and kills off sperm.
