PA or similar piercing worth it?

So I’m new to this but my gf mentioned wishing my chastity was truly inescapable in terms of pulling out (I’m being good as discussed in my prior post). We briefly discussed piercings to make that a reality. But it’s a big step, and I understand it takes a long time to heal and can affect urine flow depending on the type of piercing.

I’m wondering what people’s experiences are with piercings (PA or other) and chastity. How long was healing process, how long away from chasitity, new issues arising with maintenance once in chastity, and is it worth it in terms of the added level of control etc given to partner?
