I’m on my 4th or 5th Stealth. It’s just now that I’m getting the right fit. When brand new I do experience problems urinating and the glans does get cold. As time goes on it does stretch out for a better fit. I’m currently using D24. I use it to train my foreskin to stay retracted. Overall it helps. I use it at day & night but most nights I take if off in the middle of the night. This size has been the only one that has not came off while exercising….Fortunately, size is not a problem for me as it can become 8”. I’ve wanted to try the corkscrew but I’m afraid that the bulge would be beyond noticeable. Already it’s very noticeable, where it sometimes looks like a boner.
