Bird Cage chastity
I recomend this chastity device because it is comfortable to wear 24/7 and works for real. It comfortably traps the guy's balls between two rings and they cannot be pulled free, making the device absolutely unremoveable without the padlock key. My girlfriend decided it would be fun to permanently chastize me, and she did. Instead of the padlock, she took a small stailess steel bolt and locking nut, coated them with JB-weld steel epoxy and screwed them together through the padlock hole. Since stainless steel cannot be cut with a regular hacksaw, I can't remove the locking bolt. I have tried to hacksaw the cage itself, but all the hacksaw does is lightly scratch the metal, and I don't feel like putting a huge amount of cutting effort on something that is snuggly covering my balls and penis. My girlfriend thinks this is hilarious and uses her vibrator when we go to bed at night. I am guessing I will eventually manage to saw the damn thing off, but not in the foreseable future. But definitely before I have to get through airline security. My girlfriend has really pissed me off about that, and she still thinks it is funny.
