I like to wear cock rings at times and a 2 inch diameter ring fits me pretty well. The thicker type rings add just enough pressure and tightness to be very effective and erotic.
Recently I was looking at a small length of smooth chain that I have that I sometimes use for bondage. I tried fitting the chain around my like a cock ring and it worked pretty well. Over a little time, I have come up with the following idea.

The chain at it’s longest creates a ring just over 2 inches in diameter. If I move the lock however in to the second link, then the ring is obviously smaller, about a 2 inch diameter at that point. I have moved the lock to the 3rd, 4th and even 5th link to see how it would feel and could I wear it. At link 5, the ring is only 1.5 inches in diameter, way more tight than I have ever worn or could put on as a solid ring. At link 2 and 3 it is tight but not too bad. At link 4 it starts to get really tight, and at link 5 it is tight to wear it become very uncomfortable pretty quickly.
I have developed a game of sorts now with the chain. I start at link 1, and edge once. After an hour, I move the lock to link 2 and have to edge now 2 times. After another hour, move to link 3 and edge 3 times…. Etc. The challenge is to keep doing this until I get to link 5, edge 5 times, and then cum at the end!
It is a very difficult tease to endure. It gets uncomfortable for sure, and I would caution anyone to know your size limits.
But I thought all of you creative people could use this as a start and even improve on the idea. I look forward to all of the comments!
