Chastity and orgasm denial discussion

Hello everyone, Has anyone else dealt with noticeably swollen testicles while wearing a chastity device? I’m using the CB6000 specifically. What concerns me isn’t the testicles themselves swelling, but rather the scrotal sac appears puffy—for instance, the area where both balls meet at the bottom of the sack seems to get swollen somehow. Taking it out usually resolves the issue within an hour or so, though it can be quite alarming. Right now my balls are hugely swollen—almost making my scrotum feel completely tight. There is no pain involved—it just feels like they’re filled with water, fat, or something similar. Has anyone else had this happen or know what might cause it? SM
