why is it hard for men to pee if we have an erection brought on by the need to pee?



Especially at night when you wake up with a piss boner

In: Biology

So basically your urethra has a Y shaped junction with one leg for pee and one for ejaculate and the final leg towards the exit. Getting hard shifts the urethra to line up with the ejaculate path.

You get erections because you need to pee??
