I'm a 54yr old that semi recently took the plunge on metal stretching weights. I've used silicone and rubber stretchers in combination with smaller stainless rings for yes without gaining any real stretch. I stumbled onto this reddit and took the advice of starting small and went with a 10mm from chaingang. It wasn't long before I ordered a 20mm. I've been wearing the 10mm on my walks while freeballing, enjoying the nice swing and leak effect. As of last night, I was I'm able to stack the 10 and 20, so I guess it's time to shop for a 30mm. I'm considering a bullet but I'm not sure. The wife thought the idea of weights on my balls sounded crazy but she's really liking all of it. She likes the look and the fact she has a nice little handle to grab onto as well as the weight hitting her clit from behind. My goal if you will is to be able to put a 40mm on and wear it all day.
