Chastity and orgasm denial discussion

Hello everyone! I’m just joining the forum. I recently picked up a MaleChastityNow Contender, but it seems like there might be an issue with how I measured things, and I’d love some advice on what went wrong.

I own both 2” and 2 1/8” base rings, along with options for 3/8” and 1/2” gaps. The 2” ring feels about right; I can slide my index finger up to the first knuckle without trouble. However, when I put on the cage, my scrotum swells significantly and becomes quite firm, feeling overly compressed. Even switching to a 1/2” gap didn’t resolve this tightness while wearing the cage, so I’m wondering if perhaps I need a larger base ring instead.

I also tried out the 2 1/8” ring, where my entire index finger fits comfortably inside. Yet again, once the cage is secured, that same super-tight scrotum feeling returns despite having enough room between the ring and the cage (with the 1/2” gap).

Anyway, any tips or suggestions would be greatly appreciated!
