New to this. First time I had something up my urethra, except for the one time when I was catheterized. Thought I would give it a try. Ordered the 8mm plug and it seems to fit without popping out. About a quarter of an inch does pop out, but that’s all. A little uncomfortable for now on first wearing, but I hope that will decrease as I get accustomed to it. Would have been nice if the ring on the end was about 6 gauge. In all, a nice piece of penis jewelry. Doubt if I’ll wear it 24/7 – yet.
A caveat – before you try to pee through the plug, be sure that the tube is clear. Mine came with some crud in it.
