I have several c-rings. I don't wear them at my club. My use of them are strictly sexual in nature.
Top marks to Graydeck for being honest enough to admit the reason for using them. It's a shame some of the other cockring wearers on here cannot be as truthful, instead of making silly excuses and expecting us to believe them.
I wear one. Its a piece of jewelry usually a fine gold band . Just like a wear a chain around my neck. Kinda similar to being shaved smooth (wich I am ). Its esthetics . Interestingly lots of opinions. Not as though some ones walking around with an erection .
