I told my wife we should have one as a punishment. I’m glad she declined. Not sure I understand the practicalities at all.
It's not practical at all, I think that's the point. Honestly, I think having it for a punishment is the perfect use for it. No way at all to direct a stream of urine where you at least have some ability to control it with other devices. Also, the part where you basically have to just let it flow and waterfall over your balls adds to the humiliation. I just want one because I'm weird and am starting a collection of different chastity devices to choose from for my wheel of fortune on Chaster.
I think I'm going to have to get one, and better still, block the holes and add new smaller holes (but more of them) around the shaft so it can't even drain properly, and nappies would become essential.
