Chastity and orgasm denial discussion

I’ve been using a penis altar (PA) for years, aiming to boost security while wearing a chastity belt (CB). I got myself a PA cable, but the moment I put it on, I realized there would be an issue: the cable tends to pinch my foreskin against either the PA ring or the CB cage. Now that I’m back in a CB, I’m curious if anyone knows how to avoid this pinching with a PA cable, or other ways to use a PA to make CB devices more secure.
