Can weights help your penis size?
Penis weights work by hanging small weights off the end of your penis to stretch the penis and have length gains. This technique is claimed to work by a few but as no effect on girth gains, impotence, ejaculation control etc that the pumps/tablets and natural enlargement sites help with. The  procedure of using weights can be incredibly uncomfortable and gains take a long while. You must also be careful not to use too many weights or you could cause your skin to tear and permanent damage and scarring. Many sites offer warnings on using weights (often the competition) but my feeling is defiantly OUCH!
