im completely new to the site and Penis Enlargement in general.im 20 i have 7x5 penis..now i have started doing the "DLD's First Routine" today was the second time iv ever done it but what iv notice is after im done stretching and jelqing i measured my penis and instead of being 7inch erect its 6.5 erect and my erection is not that hard anymore aswell.So is this normal or am i doing something wrong?
