a big heavy soft looks great but I'm sure there are some disadvantages. A soft cock is supposed to be convienient when it's soft, rather small and not a bother. I think I could control the bother of having a large floppy soft with the right kind of underwear.
All things aside though, there's nothing more embarrassing than trying to hide a cock that's too showy (or semi) when you're in a situation that it doesn't need to show.
Good problem to have though.
