And whats crazy about this IRONCROTCH is that it isn't just for men, the women that do it, once they have strengthened their PC muscles with kegels, shove an egg-shaped thing that attaches to the hanger up their snatch and hang with that.......yeah....

It is really too bad that I suffer from some bad ass erectile dysfunction or I would have been doing this shit YEARS AGO. I'm kinda stuck on curing that. because of all the kinds of Penis Enlargement out there this really interests me the most and I see it as the most long term. Because it definitely is more mental based than the Penis Enlargement practiced here(not knocking it), which is how they lift those heavy weights without ripping their cocks off.
