Right now, I often lock throughout the day. There are two things that prevent me from wearing my cage more: the cage is a little small and squishes my glans a bit, and the rub of the ring on my scrotum. I’ve exclusively worn plastic cage and might look into metal to reduce ring rub.
I’m interested in a PA-secured cage with a ring (as opposed to ringless one) because I’d really love to be able to completely prevent pullout and the ability to jerk off (when the cage is on). I’m self-locking now, but I realized that I have a big fantasy of being able to hand keys of an inescapable cage over to a future partner/keyholdler. To have no ability to pull out or self-stimulate and be completely powerless to them in this respect is hot AF for me. My cage is getting tight just thinking about it lol.
It sounds like you got a good thing with your Mistress going!
Thanks :)
