Chastity and orgasm denial discussion

Hello, I have a CB-3000 and sometimes I lock myself (I’m also looking for a KH but it’s not the subject). But since few weeks, when I get very exited, I can have an orgasm (and I say orgasme no wet dream or precum) inside the cb. This can be at day one or on another day. When the cage is on, i don’t fillin the cage when I haven’t erection. Do you think i have to get another cage? shorter? in steel? Or they’re a solution with the 3000. Thanks for the answer.
