For guys like myself with compulsive masturbation issues, this thing is a god send. I have been locked in mine for close to a month now - keys belong to a straight friend who has had alot of experience locking up the opposite sex and i would suggest anyone that tries chastity find someone with experience for the key holder- and i have to say it's easily the most comfortable chastity device i've ever worn, and definitely the easiest to clean. It will not completely stop an erection, as i can get about 50% hard, but what it does stop is masturbation. i have tried on a few occasions after first putting it on to achieve an ejaculation, and i couldn't get enough stimulation to even start feeling it, so i've given up on that entirely. It's also the most secure non-metal device out there as the locking mechanism is anchored in the piercing itself. As for the PA ring, i would suggest sizing up to at least a 4 gauge ring before trying to wear this. My pa was at a 0 gauge before i put this on, and it was a breeze to put in. i would highly recommend this device to anyone that wants to try chastity play, or even for those who are after long term chastity like i am (although a metal device is more secure and would score higher marks simply because of that).
