I started to quite by necessity. Im 54 y/o now and a little more slower to respond these days. And after a bit of stroking, my dick starts to get somewhat desensitized and I start to lose my erection which is where the cock ring comes in. Im 6 3/4 inches by a tad under 6 inches in girth. I can tell my wife likes the added girth that the cock ring causes. It's not a lot but there is some girth addition. She'd never admit to me that thickness matters but I know it does by her response when I put my dick in her while using it. I use one of the thick rubber rings and I almost have to pull out my pubic hair to get it off after I'm done with it. I've seen those solid metal rings in pictures but for the life of me, I can't figure out how those guys get in and out of it. How can one have a hard on and still get that thing over the dick and balls?
