Don't Stare

Another benefit of these so-called "bathing suits" is that sexy people look sexy in them. And while no one would argue that taking in the sights is part of a pool party, there's a very fine line between appreciating the beauty around you and getting pepper-sprayed because there's no way to hide a boner in a bathing suit. So take it easy, perv. Staring limits are a half-second without sunglasses, and 3 seconds with sunglasses (and that's pushing it).
