Chastity and orgasm denial discussion

Hi everyone, I’m starting my first thread in the community. I’ve been reviewing the sizing guidelines for Queen’s Keep by Mature Metal regarding the space between the base ring and cage: Measuring that gap isn’t straightforward. Most buyers (about 90%) go with the 3/8″ size and are satisfied. Those who have practiced chastity longer often choose the 1/4″ because they’ve stretched their scrotum. Newcomers with a high, tight scrotum usually prefer the 1/2″. I’ve also noticed several men mention having either a high/tight or low/stretched setup and how that impacts sizing for devices like ball-trap types. Question: How can I tell if my scrotum is high and tight versus not? I’m unsure what standard to use when comparing myself. This query focuses on the MM Queen’s Keep but likely applies to other ball-trapped models too. I’d appreciate any guidance! Looking forward to your responses. Thanks!
