Chastity and orgasm denial discussion

Hi everyone! I’m Erika, a thirty-year-old sissy. After discussing chastity with my wife, we decided it would benefit our relationship. We ordered the CB-6000 device; I measure about 3.5 inches soft and seven inches erect, so hopefully, it fits. My main goal is to fit into a CB-6000 because I really want to feel smaller than usual. We’re also considering the Aneros Progasm for milking. Since I haven’t been milked successfully before—likely due to my frequent masturbation habits of one to three times daily—I have two questions: Is the Aneros Progasm effective, or are fingers better? (I can take a fist size, so I’m wondering if it would help me.) Secondly, regarding penis extensions: My wife plans to keep having sex with me until she finds another partner, provided I don’t come. We’re looking at the Thick Ur Dick because my erect length usually prevents me from fitting into most closed-end extenders. The question is, will this device sufficiently prevent me from getting off? Sissy Erika,
