I got the sizing rings from MM back in January and took a couple of weeks to measure myself. If you’re considering ordering from them, start with those.
Chose the WM cage with a 1/4” gap. The diameter is 1 1/8”. Picked up two base rings: an oval single ring at 1 5/8”, and then a round double ring at 1 11/16”. Began in mid-April wearing the double round one, which was fantastic. After about nine months with my CB6000s, I knew by day one of using WM that I could part ways with my plastic friend.
After three months with the 1 11/16” double ring, things started feeling looser; in the morning, I’d find the WM had slid down. I decided to give the 1 5/8” single oval a try. The fit felt much tighter. Sliding at night stopped, but scrotum burn began. Then I recalled another post about turning a single ring into a double one to fix that issue.
Two weeks with the 1 5/8” double oval and it made such a difference. No more burning. Yard work, biking, painting—all totally fine. Reached four ruined orgasms thanks to my KH.
