99%? And you got that stat from where? I believe it is totally made up. Again there is a question of truthfulness.
Well it is obvious that that your perusal of medical journals and research just may be a bit lacking. I have 2 mates that I have played golf with for 20 years who just happen to be dopey urologists.They knew what jelqing was way before I knew. Do they think much of it? Well not really; they seem to find issues with trying to mess with healthy tissue but they know it exists and then have treated patients with issues pertaining to that. You can have your views as well as I can have mine.
