Any Long-Term Health Impacts?

Hello.. I’m a 75-year-old straight man in great shape, blessed with an awesome and very understanding girlfriend. Up until now, my chastity has been mostly playful foreplay. Now I’m thinking about adopting more of a schedule: wearing the cage 24/7 for blocks of 3 to 4 days, followed (hopefully) by a release lasting a few hours so I can enjoy some recreation before starting the cycle again. I’ve been testing out cages in different sizes. The smaller ones, around 2 inches wide, feel very comfortable and stop erections well, but I worry about potential tissue compression causing issues like ED. Using a longer cage (about 3.5 inches) helps ease my concerns regarding that compression, though it does permit semi-erections which can be quite uncomfortable. As you know, there is plenty of information online. Some reports mention ED appearing after very long continuous periods in the device, with some evidence suggesting this might resolve over time once released. Another factor to consider is whether people had pre-existing ED issues before starting their chastity journey. Thanks for your advice and perspective.
