Have to be a little nutty to keep going.
I agree with some of the prior posts that you have to have a bit of a screw loose to keep doing this. It takes so much darn time and why? My wife thinks mine is fine or big already but for some reason I want more. I think about quitting every day I do it and then the ruler shows a tiny gain and I get the urge to do it even more. Maybe some shrink can diagnose our problem? I want to keep trying until I reach 8x6. But I think most people are not dedicated to go at it long enough to get real results. And the more people who do it, the more that will get injured. Soon you will hear only stories of poor men who exploded their cocks doing PE. I can just see the media having a blast with that and ignoring all the people that it has worked for.
