Chastity and orgasm denial discussion

hello everyone, I’m new here. It’s been three days since I got locked up and eight days without an orgasm. My KH has been teasing me and getting some pleasure out of the situation. At first when I was put in the device it felt fine, but now the ring seems tighter and my testicles have swelled up a bit—they aren’t blue or numb though. During cleaning breaks, I feel like I’m on the verge of ejaculating, yet they don’t hurt to touch. I have a few questions: Is this normal? Will these symptoms fade as I adjust to wearing a chastity device (CD)? How can you tell if the ring size is right? And when exactly do you need to orgasm? Thanks for reading and helping out. My KH and I are newbies but we’re enjoying it greatly and want to continue, provided there aren’t any health risks involved.

Best,
