Adjusting to Pain from a New Cage?

Hello, I have a question about pain from the chastity cage. I’ve read that you need to get used to the cage and that it can be uncomfortable and even a bit painful at first. I’m using the “Cock Cage 2,” and I think it fits quite well. The ring is tight, but I can still fit a finger between it when I put it on. The cage itself also fits quite well. I’ve been wearing the cage for a few hours at a time. On the first day, I wore it for 4 hours. On the second day, 6 hours. On the third and fourth days, 9 hours each. Yesterday, I wore it at night for a total of 14 hours. It was uncomfortable at night but bearable. Today, I only wore it for 4 hours because a few spots on my skin feel irritated, and I don’t want to risk chafing. I use body lotion for skin care. When the cage is on, there’s about 8mm of space at the top of the ring between the cage—what is that actually called?—and the ring. Skin gets pinched in there, and over time, it starts to pinch more. It doesn’t seem like there are any circulation issues, as the skin color doesn’t change, and there’s no tingling. It’s just the pinching, so my question is: is this something I have to endure until my body gets used to it? Since I’m quite tolerant of pain and have read everywhere that pain isn’t good, I’m wondering if something might be wrong? Lastly, how should I increase the wearing duration? How did you get used to it? When should it be possible to tolerate the cage for a whole day? Thank you for your answers!
