Chastity and orgasm denial discussion

Hi everyone.

My partner and I are newcomers here; we’ve been lurking around this community for about a month or so. The background is that I began with the largest ring paired with a substantial spacer, eventually settling into a comfortable and relatively secure fit. Since my keyholder has a warmer constitution than mine, she allowed me to come during intercourse. Now, however, I’m struggling to find that sweet spot again: either the ring feels too tight, causing a burning tingle in the skin of my scrotum, or it’s too loose, leading to retracting testicles and the cage slipping off. Is this normal? Also, after my morning shower, my scrotum seems to pull up almost completely, causing the cage to fall off. Any tips on this would be appreciated.

Best regards, trym
