Keyholder Feels Guilty While Seeking Guidance

My spouse and I are newcomers to the chastity lifestyle. I’ve been interested in enforced chastity for a long time, slowly coaxing my wife into embracing it as one of my sexual kinks. We have now entered an enforced relationship and have continued with this for two months. My current longest lockup is 9 days. My wife feels bad about denying me even though I’ve explained that’s what I want. She has begun to embrace the lifestyle more, enjoying that she holds control while I’m locked, but she also feels guilty if I don’t get my orgasm regularly. Any advice on helping smooth her transition? She says she wants this but is scared of it.
