I do but don't waist ur money on one. Make ur own. Get some old tights and cut the elastic away. Then cut one of the legs wide enough for ur undercarriage. Slide the elastic u cut off through the piece of leg u cut so it sticks out either side. Pop ur legs through pull up and push ur balls back where they were when u were a nipper before they dropped. Fold ur penis down and back. Pull up tight as high as u need to. Not very comfy but u get used to it.
Hope I explained it well enough. Not that great on the computer or even writing.
