So my partner is very submissive (very!) and often won't be allowed to cum when we play. I'd like to take it a step further and lock his cock in chastity.

Initially he was quite excited about it, but when I actually got the device he got apprehensive. We tried few times for short periods during play and it was hot (he even cummed through the cage), but he's complaining about discomfort. He also doesn't really want to wear it outside of play, what I'd ideally want. Since we're long distance, it would amazing to get him to the stage that he wears chastity during the weekdays, but is allowed out when we meet.

So here's my question: how can I talk to him about it? I tried giving up on this idea, but it's such a strong fantasy, I've ended up locking myself a few times 😅
