No family member told me about PE. Although I had an online friend on AOL when I was in my pre-teens to early teen years. He said something about squeezing mildly making the girth larger if done long enough over a period of time. After feeling so inadequate from watching porn movies with the big-dicked stars, I thought there had to be a way to increase the size of the penis, much like muscles. On the KaZaA network someone was hosting this free PDF (Document) about Natural Penis Enlargement. It explained the history, the theory, and most importantly, the techniques and subsequent routines. It explained stretching, jelqing, squeezing, and kegeling. I performed a few jelq sessions at 15 and noticed my flaccid was bigger.
The night before junior year of high school I made a commitment that I was going to PE religiously through the rest of high school, going from average to huge. I worked diligently for over 2 1/2 years, increasing my penile volume well over 75%.
My grandfather and dad both walked in on me doing hanging exercises. They have never brought it up, although they have noticed my ADS devices which I have worn over the years, telling by their glances.
I don’t think there’s any difference between bringing up working out or PE. In fact, I would want my sons to at least know about both from an early age, if not perform them!
