It's real I seen something similar to this on a programme called the perfect penis, there are quite a few guys doing it, they inject silicone into the penis tissue and the scrotum, god only knows why lik. As the guy interviewed on the programme said he couldnt even get aroused, so basically your left with a big ugly looking dick that doesnt do jack. I remember the narrater of the programme mentioning at the end of the programme that the bloke in question was in hospital with silicone poisoning or something like that.
