Hi all, I have seen a fair few posts now about cummin in chastity and how long is safe to be locked for etc etc. This is my PERSONAL experience. I am locked 24/7/365. I'm in my mid 30's and a relatively healthy male. I am locked in a mature metal device and have NO hygiene issues using it. I don't get released for cleaning cause I can easily do it in the device. Now this is from my experience and it will probably differ person to person. Chastity has caused me shrinkage but only a couple of inches. Night time erections do cease and get easier. Yes I do suffer with getting hard after being locked for so long but it does eventually start to return and I am able to get full erections after a while. I don't get milked cause we have found that after 3-4 months I will suddenly get a strange sensation in my penis and if I squeeze the muscles then I can force out a large amount of cum (with no stimulation what so ever). So in summary (my experience) Yes it's possible to be locked for years. No you don't need to cum via stimulation. But you will suffer shrinkage/ erections problems and your first proper cum (based on my last cum after nearly 2 years locked) will be very painful and so thick it could resemble plastic. Again I state that this is MY EXPERIENCE!!
