Looking good in your Xtube jerk-off video certainly doesn't require that you be so incredibly ripped that you could grate cheese with the razor sharp ridges of your abdominal muscles, but it doesn't hurt your chances.
More and more we've come to understand that some guys are just so hot it isn't fair. Sure maybe some day we'll be able to slip our lithe little body into a tiny pair of briefs and not look like a deflating balloon with a rubber band around its middle. In the meanwhile, there are always videos like this to get off to.
