Chastity and orgasm denial discussion

Greetings everyone I’ve been lurking here for a bit and really liked the chats, tales, and info. Now I’d like to be more involved. First up, a sizing query. I own a Jailbird. Wearing just the base ring feels great; even overnight is fine with it. Adding the cage doesn’t hurt either. Evening erections aren’t an issue at all when starting out. The main trouble comes from those early night erections. Once they hit, getting back down is tough. The blood seems trapped inside, and the hardness won’t subside. I have to take off the cage. So here’s my question for you seasoned chasers. What causes this? Could the base ring be too tight? Maybe the cage length prevents erections from swelling enough? Another cause (perhaps a gap?) Or is it just the wrong model (I’m considering picking up a Chili Cage)?\nAny tips or answers are greatly appreciated.
