Introductions discussion

While I wait to find a moment that feels right to bring this into my wife’s life, I’ve been considering if it might make her first lockup easier…I was thinking we usually have sex once before her period arrives, and then stop during the time she is bleeding. She gets a bit miserable (she is perfectly healthy, but if given the choice she would skip having her period)…so maybe my first lockup could start when she begins her cycle, as though I am enduring it alongside her to some degree. Then she can choose when to let me out for some “fun”. generally after she gets in a good mood quite quickly. So this would likely work out as a 1 week starter. Since she sometimes enjoys being submissive and having me take the lead (generally about once a month after her period), perhaps part of our dynamic is that I stay out during that specific week and then go back into lockup when she no longer feels like it. Any Thoughts on this approach?

I don't suggest you introduce her to chastity by setting a timetable around her cycle. Later, after you two are firmly into it, a suggestion an explanation of the benefits would be ok.
