Chastity and orgasm denial discussion

Hi everyone. My partner just experienced her first major climax while I was wearing a birdcage…For me, the sensation was intense as well, though predictably not quite enough to trigger release…She mentioned that the cage provided more vaginal stimulation than my bare cock would have, even though its downward curve meant it could only nudge at the entrance of her vagina. She’d like it to go deeper. I attempted wearing the cage with the curve facing upwards and actually managed it, but it came at the cost of badly squashed balls and some minor cuts and blood blisters on my cock. Those will heal up fast enough, so that approach is still a possibility, though I can’t quite figure out a position where the curve enters correctly while we cuddle simultaneously. Does anyone know an upward-curving cage? Thanks for your assistance.
