I made my own... I have a PA... specifically to secure chastity... I had a PA5000 but like I had read in reviews it eventually split. that had to be modified too. I found the problem with them also is they are too short and I could still jack off, also the gaps caused oedema.. so even that had to be modified. Sooo I bought some aluminium tube (its easier to cut and file etc.) and some sugru and experimented with different lengths etc.. finally got the size perfect. It is secured by a short princes wand fastend with a security screw through a silicon flesh tunnel, which is now covered with sugru so totally tamper proof.. and trust me impossible for me to cum. My wife has a free pass to fuck anyone she wants and the secure knowledge that no matter how hard I try, real men can cum in her and I cant even wank.
Cleaning... hmmm well sitting in the bath i use a syringe to squirt liquid soap in to the tube and vigorusly shake LOL then flush it out.. and the swab a Q tip around.. then repeat..
This is early days been in for just a week but now expect it to be permanent.
Why hmmm because I love my wife with all my heart and soul and my cock can no longer perform to her satisfaction... yeh done viagra and all that. So I have to get inventive and I wanted to make it up to her for not being the man she needs. I gave her the gift of all my future orgasms and she eagerly took them. "Good this is great. I dont want you having another orgasm .. EVER!" It's what she wants... Its what she deserves.
