Sorry if others know more about chastity play than me and are therefore familiar with these, but I was browsing Ebay for anything amusing and I came across this. This was from a genuine Ebay auction that ends later today. I’d never seen one of these before, it just looks like an antiquated bathroom tap that’s been ripped out of a London Voctorian terrace to make way for glass tiles and a fucking wet room. Read about chastity play here if you really want to – sounds more like torture to me, but I have to present some information if people want it 
It boasts a safety latch to stop unwanted tightening happening once it’s in place (I bet now all the men have uncrossed their legs and are sitting comfortably again) and is supplied with just one key – so might be prudent to make a spare. There is always the other alternative of not forcing your penis into a 35mm diameter bent tube, but judging from the bidding history on the soon-to-end item I’m guessing that many people see this kind of thing differently. I just hope that whomever they are they are buying it for their own personal needs/desires/gratification, and not as a present for their teenage son…
After doing a little research, I found out this design to be called the Houdini Cock Lock – haha I couldn’t make it up.
