shaven_cock,
I've already gone down that road. I was in chastity on and off for around 3 years. 24/7 for around 2, and that, combined with herbal breast pills (Pueraria Mirifica), and age has accounted for what I've lost so far. Most of the time I'm way too small for a chastity device. I've looked at some of the inverted cages out there, and while they look very attractive, I'm not sold on them. This is because of the urination problem. I don't particularly like the idea of a catheter tube going into me. Although it would only be a couple of inches, I just don't need the risk of a UTI. Without the tube, it would be way too messy. Piss getting everywhere every time I have to go? I'm getting older and have to piss more than I used to, so it's a deal breaker.
Anyways, I like where I'm at now. Up inside me with just the head poking out most of time. If I want to cum I can, with or without the Cialis. And my breasts are coming along nicely.
