Chastity and orgasm denial discussion

Hello everyone. First off, as a new member here, I’d like to say hi! Big wave:) I identify as a bisexual submissive. Unfortunately, the dominant figure in my life has just left (it’s not tragic; he got a new job far away, and I can’t move with him). However, right before we split up, I agreed to undergo chastisement, and he believes I should keep going until I meet another dom or domme. With that goal in mind, I’ve begun wearing a CB-6000. I put mine on yesterday, but I’m encountering some issues where I’d appreciate a second opinion. Any assistance would be wonderful. To begin with, I am what you might call a “show-er” rather than a “grow-er,” meaning even when flaccid, my penis is quite substantial in both length and thickness. Consequently, regardless of how much lubricant I apply or how firmly I push it inside, a good portion of the shaft remains outside at the rear, bunched up with the glans pressed right against the cage’s end cap. It isn’t painful or uncomfortable whatsoever, but does this matter? Will it hinder erection attempts? Also, would switching to a longer spacer help? Additionally, I must use the largest ring size available, yet even that feels somewhat snug—not uncomfortably so—but I’m unsure how much restriction it places on my blood flow. With everything in place, I can just slide one finger between the scrotum and the ring, so I wonder if this gap is sufficient or not. There’s zero risk of pulling out. Thanks very much for any advice you can share.
