I have been wondering about a device for some time now and have returned to discover the PA-5000 could be what I need... I have a PA wearing either a 4ga or 6ga ring. I measured my cock the other night and I believe it is 1.25 inches but that is the size of the largest PA-5000 and they say you should go one larger (1/8th more) to get a good fit but which allows you to clean. So what do I go for? So far I have read on the net everyone saying you should go smaller so it is tighter, but want your opinions... Please Advise. Who knows, I might have got a little bigger when I was measuring! I have never been in chastity before, so don't want it too tight, not into pain. Thanks and look forward to your advice, so that I can order one.
