Chastity and orgasm denial discussion

since i am new to this site, i am a bit uncertain whether this is the correct place to ask my question. i have been wearing the cb-6000 nearly around the clock for the last two weeks. before that, i spent three weeks practicing with it to get the spacers and rings sorted out. on sunday, april 4th, i handed over the keys to my wife. like many women, she was somewhat hesitant about this whole chastity idea at first. she let me out on sunday morning for a quick encounter, which indeed proved to be brief for me. i was so horned up that it was hard to stand still or hold back ejaculation. however, my question is… when she said we should proceed, i struggled to get an erection and keep going during intercourse. i had to remove the device today for a few minutes; she told me to become fully erect again, which turned out quite challenging. while stroking and touching feel great, it simply isn’t as firm as it was just a couple of weeks ago. does wearing it for a long time along with intense teasing cause issues with erection quality, or am i missing something else?
