I simply hated traditional CD ball trap devices. Never got better with nightly erections over time. I needed a solution to make CD comfortable and likely more accesible to a wider audience. Ended up getting a PA and it was whole less of a bid deal than I thought it would be.....easy healing, and with a light weight device, you don't even know it is there. Didn't really believe that erection elimination was the end all for everyone who was interested in chastity. Thus designed this to maximize hygiene and easy tease, while still preventing orgasm. Some might find it too naked of a device, but in keeps me chaste and doesn't wake me up at night....more like my cock was wrapped in tight gauze. No issues with urination as the PA hook stays close to the end of penis, not causing the surface tension that tends to widened the spray. Also because it is light, can wear as a 10 gauge so urine only occasionally leaks out the bottom portion of the piercing. Press down on the head lightly and no urine leaks for me. The key and lock are also 3d printed and once the position of the key grips are changed, only one unique key made every time.
