FWIW, I think you should sag your jeans because your proportions aren't balanced, not because you have a penis. The other pictures you posted are way more proportional (with the possible exception of the Context pic).
I agree that the proportions in my previous pics looked whack.
In my opinion the belt has helped to fix the proportions.
I don't really mind if it makes my legs look a little long, because IRL i'm kinda short.
