My girlfriend and I read your column religiously, and I have you to thank for being comfortable enough with my kinks to tell her about my interest in BDSM. She is very GGG and has indulged all my kinky fantasies and discovered some of her own. Our latest adventure has her locking up my dick in a CB-6000 male chastity device. The play/sex has been super-fun so far, but we want to be aware of any health and safety concerns, specifically damage to my penis. We’ve had the device for almost a week, and I’ve been doing a ton of research.
