K.I.S.S.
keep it simple silly!
The penis evokes so much curiosity but this curiosity has a tendency to disillusion us, as men, largely because it is so difficult for us to believe Penis Enlargement works. Since the penis, mainly the LARGE penis, or the potential to get a massive cock, stir up so many feelings of unbelief, non-belief or suspicion to what is right in front of our eyes, we need to examine our real motives for any inquisition.
What I mean and how it applies to this thread is this; We know Penis Enlargement works or we would not be here. We see men gaining everyday, we hear the stories, chat with our fellow members about the gains we make, WE SEE IT but still there is always this nagging doubt that it may not really be working or we somehow have been fooling ourselves to the gains we have witnessed right in front of our eyes. This "magical doubt" that lurks in every man, even more so in a typical Penis Enlargement'er because it includes the penis the center of our physical manhood, this doubt that includes an equally nagging faith that drives us to continue also causes us to read to deeply into something so simple it is silly.
Enlarging the penis, specifically girth, in no way is effected by normal sexual activity. We can read into this topic for months even years, and some of us vets have done so, but still come up with the same answer...We do not know.
What I can say is this; I have studied the penis exhaustively. I have tried every conceivable theory, routine and system around girth. I have listened, read and learned every possible theory and concept from urologists to newbies around girth, Penis Enlargement and sexual activities effects on these topics and my personal theory (or should I say hypothesis) is this; No, sex, masturbation, or any other "normal" sexual activity (look up normal in a conservative dictionary

) has no effect of gains, but not limited to girth.
When my angel, Jennifer, was still with me I did my girth work right before sex almost everyday. During sex I would ejaculate. I did this for 3 years straight (my first 2 years I spent researching other sex/girth theories) and my girth went from 4.75 to 7 (at it's thickest after training) My length went from 6.5" to 10.5". My erect girth, after no Penis Enlargement for 48 hours, is 6.5" and my non-bone pressed erect length went from about 5.5" to 10".
I am not sure if anyone has made gains like this, or have proven them to my extent, but from m own person experience, I would not change a thing.
