I think I may have started…

This is the main part you have to tell her. With or without chastity

Don’t say this. Not at first at least.


Reading your other posts. I truly understand you are self locking. You want to be comfortable in your cage before you give her the keys. When you introduce chastity, you want to talk about the fun parts of it.
Not about the “technical” parts like hygiene, chafing, sizing etc.
Get that part sorted out for yourself, then introduce her.

I’m a bit in a similar situation where we are testing our boundaries. We both have a key. She can use it to unlock me for “fun”, if she wants. I have a key to take care of the “daily life”.

 

That's not dissimilar to us. And it works for the most part. Though I hasten to add that being submissive helps, even though my Wife is not at all dominant.

She may control your cock, but you have an equal say in the intimacy part. Having my cock taken from me could and did enable me to focus on service and intimacy. She doesn't want sex. Oh well. We have never been more in love.
