Chastity and orgasm denial discussion

Ok so I’m 23 years old and have been with my Girlfriend for about 2 years. We currently practice chastity every now and then. I own a CB6000s. I’ve wanted a Jailbird for a long time and finally decided to order one, so next week I will be placing the order. My girlfriend and I have been talking, and we both think it would be fun and a good idea if we start our marriage using chastity. I had sex in a past relationship but it didn’t last long; we only had sex 8-10 times total. My girlfriend has never had sex as we are waiting until marriage, which is fine with me. She thought that at the time I propose I should be locked and hand her the key. She does not want to just keep me locked from that point on forever but she wants to keep me in 100% lockdown for at least a month or two before the wedding. And have my release on the honeymoon. She is wanting more input on how long I should be kept locked before the wedding: should it just be 2 months, or weeks and two for every time I have sex? What are your thoughts and ideas, and also what should be my release time after the honeymoon? Thanks to everyone who reply.
