when i first started pe, i eneded up with a baseball bat penis. i didn't mind too much because it came in handy while slapping the old lady in the face. i mean, since i am a ball player.
anyways,
after finishing the phase one routine, the base of my cock ended up becoming bigger than the rest of my entire dick. it's also hard as fuck when i get erect!
i don't think there is any way to maintan this baseball bat effect, i think it's just a temporary side-effect of pe.
