I was quite skeptical at first about the PE exercises being effective. But, figured since there is nothing to be gained by anyone on here lying about their results, nobody is selling memberships to get the routines or anything, I figured I'd give it a shot and see what happens. Glad I did. Started a couple days less than a month ago. Honestly I haven't quite given it my all either, miss a day here and there things like that. But i started out just a hair (1/8" or 1/16") under 6 on length and about 1/8" under 6 on girth. Now after a little less than a month, I'm a little over 6 1/2" length and a little over 6" girth. Have gained between 1/2" & 3/4" in length and about a 1/4" in girth. I tend to think that's pretty good results in such short time. Now that I'm a believer, plan on being a little more devoted and trying to hit the 7 1/2 to 8 mark on length. I'm thinking on girth I'm doing OK, maybe hit about 6 1/2 or so on girth and be happy.
