Here is a new kind of underwear. It is made by International Male or Undergear(the reason for the uncertainty is I'm unsure who makes it because both of their websites say they do and amazon gives credit to both as well) and it's called the Sock Jockstrap. This is really kind of cool because it has no straps. It just has a waistband with a jock front attached. The jock front is designed so that it stays on by slipping over your penis and the elastic keeps it in place (view little thumbnail on photo for more explanation). It is not recommended for athletics because it gives no support and would probably just fall off. This is really just a novelty and would make a nice turn-on. I think that it is a really good idea and maybe with a little tweaking would be safe for sports. The main reason that one would want to wear this is for a seamless look under clothing. In other words, it doesn't show through your clothing with underwear lines because obviously there is no back and you package makes it so there are none in the front. Need I explain anymore? I don't think so. Anyways I just thought that you might want to check out this exciting new option. It is avaliable at Amazon for $9.99.
