I'm not sure if I just haven't found the right fit or what. I've been locked in chastity for the last three months or so with the occasional release and I love it. Something about metal surrounding my penis and not being able to really touch it is exhilarating. My problem is finding the proper fit for the a-ring. I've bounced back and forth between a 1-3/4" and 1-7/8". Using the 1-3/4" definitely keeps me secure. However I sometimes awake in the morning and have some edema. It also wakes me up every two hours from I'm guessing an attempted hard on. I can fit a finger up to the first knuckle but it's a little tight. If I use the 1-7/8" ring, I can sleep through the night but it sometimes feels a little loose throughout the day. I've actually had it slip off once. Of course I immediately slipped myself back in. The thing is, I'm usually a high and tight guy but in the warm weather I tend to hang a bit lower which causes the larger ring to slip a bit. I'd really like to use one ring all the time. Any advice? By the way, unfortunately I'm using a cheap off the shelf cage because I just can't swing for a MM jailbird just yet. I think this is helping zero in on a proper fit though.
