Introductions discussion

Hi everyone, just dropping in to say hello. My Wife and I are new to Chastity play. She is usually open to any new fetishes that I propose we should try (lucky me, best wife in the world ).I have been interested in chastity for quite a while and 2 weeks ago we decided to give it a go. Right now she doesn’t like having me locked up for too long, so she pretty much unlocks me every time she wants to have sex. I enjoy being edged for longer stretches because when I am at that mental state, she can do whatever she pleases with me!! I’m still getting used to the cage; the main issue is occasional ball pinching because the skin gets wrinkled at the base. Currently we are using a CB6000 with a 5mm ring. Any advice on how to avoid this? Should I get another device or a larger ring size? We both love chastity play btw… Regards
