Introductions discussion

I’ve been suffering from intense ball burn with my chastity devices — specifically the CB600s, both hinged and solid ring versions. When I downsize them, my balls tend to slip out. If I keep them trapped tight, the skin gets caught and burns terribly. Lubricant hasn’t really helped (it mostly just helps prevent slipping). It seems like I have a larger girth but smaller testicles. I’m not keen on getting pierced or undergoing permanent body modifications.
