My 2 cents on your question and Sunshine’s responsive. I think you’re coming at the PE process from the wrong angle. What is it you really want? To increase the pride you have in yourself from a “manhood” perspective, right. That is accomplished when you look down and your buddy is bigger, both FL and EL, period. My take from reading 500 threads at TPs is that the PE process, though many approach it differently, has certain common principles. When you stretch your buddy either length or width wise, consistently (as Sunshine Kid states) and over long periods, you will get growth. You’ll notice you FSL increase, followed behind by EL, and eventually by FL.
There’s a physiological nature to this PE game. The variables are: which exercises works best for you, are you under/over training, and how fast does your particular body respond. These variates will be different for each of use, but if you remain consistent you will get growth, maybe slower or faster then someone else., but you will get growth.
For example, I’m going into my 5th month. After reading tons of posts, I listened to the vets experience and focused on my length first before worrying about girth. I’ve only done manual stretches, Jelqs twice a week, and used an ADS 4-7 hrs/day four days a week. I have been very lucky with my newbie gains of 1 inch (6” to 7”) in four months. I attribute this to unfaltering consistency and not worrying about if EL, FL, or G is increasing, for I know that it will, as long as I stay on my regiment. The only time I faltered from my routine was in the third month when my Girth dropped from 5.5 to 5.25 and I added jelqs to bring it back and it did. I also went from 6 days on 1 off to 2 on 1. I found that my buddy needed the break time to recover from soreness.
At the end of the 4th month, I now notice that my buddy turtles only about 40% of when it use to, and my flaccid length has increased visually. I will not do girth focused exercises till I get within 1/2 inch of my L goal. I will not measure EL till I get to my FSL goal (I know EL usually trails FSL by about 1/2”). I will hammer at the same exercises till my gains stop (hasn’t yet) then I’ll decondition and start again. If I learned anything from reading all those TP threads it was the implicit logic that routine regularity gets the growth, not worrying this or that. Just my thoughts, hope it helps.
