I saw that on some programme about body modification. It's one thing to inject saline into your danglies - that lasts a few hours and goes away and your danglies are none the worse for wear. ( Aye, people do it. Cos I guess they like the feeling of heavy, grossly swollen danglies. You can't even fuck someone with your danglies that grotesquely swollen so I can't see the point. ) But it's another thing to inject silicone, which will permanently disfigure you.
