Frenum Piercing as a Security Measure

My wife is really starting to get comfortable with denying me, and she really likes the idea of a secure lock-up. We currently use our ribbon technique to keep me from escaping undetected, but she is thinking of stepping up to maximum security - a piercing. I am not too keen on the PA, since I like the freedom to pee standing up without spraying my pants. If she really wants me pierced, I think I would rather have the frenum piercing. Here is my question. Can a simple cable be used to secure a frenum ring through the bars of a Jailbird, back to the padlock on top? I think it would work, but I’m wondering what others do when using a frenum piercing for security. Thanks.
