i am 13. my penis is 4.5 inches erect with hair around the penis on on my testicles. i don't like sports but swimming and i don't get a lot of times to swim. the other night i was masturbating ( )
and i was lying in bed when suddenly i got this strange pulse thing in the underside of my penis, and i felt like i was peeing, only it felt thicker. it was slightly whit and a little yellow, but for the most part it was clear.
is this normal?
