We had a friend that always used to say, "Only bottoms wear white belts." Well, apparently it applies to jock straps as well. Conversely, tops only wear black jock straps. That's not an opinion—that's science!
We did extensive research by watching this one video and we have decided that tops wear black jock straps. Certainly not white, that's a bottom's color. And certainly none of those sissy hues or patters that you see popping up all over the place these days. No: black. It's serious, it's powerful, it's domineering, and it will fuck you all night long without even bothering to take off its undergarments. Oh, we're a big big fan of black, let us tell you.
