Hi! Right now I have the perfect cage size (N narrow) but I am still having trouble with the ring size.

I tried the size 1 ring but it’s way too small. I have a size 2 (curved) ring but there are a few issues: 1) my balls have slipped out a couple times when I’m getting fucked, 2) it can really squeeze/burn/cause discoloration (even with lubricant) when my balls retract.

I know everyone says the string measurement method overestimates the ring size, but I need some guidance here. When I did the measurements around my dick/balls, the absolute smallest/tightest circumference was 6.3 in/160 mm (== 2 in/50.8 mm diameter), which translates to a size 4 ring.

I know I should get an XD (or standard) ring to prevent slippage, but I don’t know if I should a) stick with a size 2 and risk the burn/discoloration b) get a size 4 (consistent with my measurement), or c) get a size 3 (one size up).

Thanks!
