Boy , I find it hard to believe ANY guys doesn't know he's penis outline is on display. Don't you think guys KNOW this, esp college age guys, who seem to be the ones most likely to wear sports shorts with nothing underneath? We're all so obsessed with our cocks and balls that it's unimaginable to be that the perpetrator is unaware his package is flopping about. I guess I do like that look on guys, but I prefer seein a dude who's wearing a JOCKSTRAP under it all. Makes for a better bulge.
