I have no skin in the game and PE worked for me. I stumbled on to here thinking they are just trying to sell something. Read some of the forums with posts from some truly messed up guys, all sorts of problems. So I thought what the Hell I'll give JP90 a try for 30 days see what happens, why not? Well it worked in my case but I'm older so the beginning results very well may have just been better erections. Stiffer and bigger? Don't know I never really paid attention. I can tell you with time I did get bigger and thicker then I have ever been. I'm doubtful anyone will go from a 4 inch dick to an 8 inch dick but that's not really important.
No women in history ever said, " I like his giant limp dick."
Most important is your dick works.
Next is hardness, them women like it rock hard.
Next up would be length and girth.
I'm 50 now and my dick is rock hard due to PE, extra length and girth is just a by product which I like but I would do PE just for the stiffness. In fact my wife said no more getting bigger but I still do a little work out once a week to keep everything go right.
