We already knew that SWA (sex with animals) was bad for the soul, but the other day we learned why it is equally bad for the penis. Just so we're all clear here, sticking a d**k in a non-human animal hole doubles the risk for penis cancer. Sure, we knew that somehow, somewhere in a very intangible, hard-to-conceptualize way, that people were doing it with animals, but we were blown away by just how many zoophiles there were out there. The stats suggested that as many as 35 percent of men in rural Brazil had engaged in bestiality at some point. But men having SWA are not only on the farm, about 36 percent of the animal f**ker population reside in big cities. So there you have it, SWA is more widely practiced than we thought.
