Hi Ms. Jenna,

Haven't found anyone, but yes he is locked up quite a bit of the time. It makes me giggle every time I see it like that.
You've made great progress in a reasonably-short amount of time moving your may toward where you want him. That's good! Congratulations!
I hope you're remembering that the fact you're requiring your boyfriend to wear a chastity device, with you his sole key holder, does not in any way imply you should limit your own sexual satisfaction. If you aren't already doing this, you might consider getting him accustomed to being "queened" by you regularly as a means of orally bringing you to orgasm whenever you wish. See:
Queening your man:
The Fine Art of Queening
Queening your boyfriend regularly will move him toward acceptance of you feeding him your cream pies (by queening him) and "cleaning" your pussy with his tongue — thus becoming, in essence, your cuntsucker — when you return from fucking other men, when you begin taking other men as lovers.*
In addition, now that your boyfriend has accepted (for the most part, it sounds like) the concept of you holding the key... literally... to his sexual release, you might also consider bringing him to acknowledge that you are the dominant partner in your relationship, while he is submissive and does things for you that you require (like, for instance, your... soon to be his... housework). A way to accelerate his movement in this direction would be to panty him, such that psychologically he comes to accept that in his relationship with you, you wear the pants and he wears the panties. See, for instance:

*As a married woman elsewhere online put it: "If you require your man to wear a chastity device, cuckolding will follow like night follows day."
