I've been looking at PE exercises and I was wondering if they would work for me. This might be a misconception, but it seems to me that these exercices only help guys acchieve harder erection, and harder erection would result in a bigger penis. My erection are always rock hard. And I mean ROCK HARD. When my dick is erected it's always pointing at the roof and pulling it down to make it perpendicular to my body is painfull for me. A lot of girls told me they have never seen a dick as hard as mine. So my question is : are there any guys who had rock hard erections before doing these exercices and still gained lenght doing them?
