Chastity and orgasm denial discussion

Alright, my mind is racing, so I’m going to try and discuss my thoughts as clearly as possible. My wife and I have played with chastity. She actually really likes it. She really likes the idea of me being her slave. She loses sight of what I find fun and exciting about it, which is giving her control over my orgasms. She just likes the benefits. A lot. That said, sometimes I’ve put on the cage in the morning without her knowing and put the keys in her purse. Then when she gets to work, I tell her to check her purse. It always excites her. But she never wants to leave it on overnight. I think she thinks it may damage the boys. Well, we just got pregnant. About seven weeks in. She has joked that after she gives birth when we can’t have sex for awhile that I better be ready to be locked. Cool. Thing is, I want to take it further. I want to go pro with this. I want to get pierced. And I’m thinking that there’s no better time than late in the pregnancy. When we can’t have sex and we’d both need time to recover. And I want to talk to her about it, but I struggle. I struggle with myself. Because when I’m horny, there is no bigger turn on than being locked by her. But after I cum, I’m like “why the hell would I want to be caged 24/7??” But I know in my heart that I want to be caged full time. I know it. It’s just a wild revelation to make. Even when she’s kinda into chastity. I just feel like this takes it to a different territory. What should I do? I feel like I have such a big opportunity coming up to really shift things into gear, but then again, we’re having a fucking kid! May be WAY to stressful of a time to even sniff the subject.
