Introductions discussion

Hello everyone, I am also new here and to the concept of chastity. As Mistress Jackie’s slave, I feel quite fortunate! Chastity is going to be a key part of my life, and I am fully dedicated to it. After doing some digging, I purchased the CB6000. Before putting it on for the first time, I read up on spacers and rings, knowing that adaptation would take some effort and finding the right fit might be tricky. However, I have two main issues and hope experienced members can guide me.

My first problem is excitement; being in chastity for my Mistress excites me greatly. Although she allowed me to ejaculate, I couldn’t become flaccid enough. I tried ice water, warm water, and thinking of unappealing topics, but nothing seemed to help lower my erection so I could get into the CB6000. It took almost three hours before I was exhausted enough to manage it. That is clearly too long and not acceptable for my Mistress.

My second problem is swelling; after wearing the device for 12 hours, I swelled up significantly, taking a couple of days to return to a more normal level. I sincerely appreciate any advice that might help me overcome these issues. As an aside, I am uncircumcised and wonder if this plays a role in whether the CB6000 works for my case.
