The urge to urinate can cause an erection?

I heard this and wasn't sure it was true... If it is what is the reasoning behind this?


Most Helpful Guy

  • The need to urinate stimulates the production of a chemical that inhibits blood flow out of the of the penis just like arousal does. That is what "morning wood" is. An erection prevents a guy from peeing (unless he concentrates on letting go) and prevents us from peeing when we don't want to.

  • It doesn't always happen but I have had it happen. It usually only happens when I have to go really badly, though.

  • Nope, at least not in my case.

  • Yea. The full bladder causes added pressure on the prostate, resulting in an erection. That's my theory. Lol

  • ya only in real bad cases like morning wood
