Just got my new chastity device in the mail today, HT V3 The Nub. It is an nock off from eBay but it works well. I want to try it on as soon as I got home and I already like it more then my cb6000s. Definitely need to play around with the other ring sizes, I am using the largest one it came with. Also some edges are very sharp, so some filing and sanding is needed on the locking hub attached to the ring. Lasty, I definitely need to trim my pubic hair.
