NewKH I’m not typically a person who likes to control/be in charge - I’m a total bottom lol.
You don't have to be a total dominatrix or anything... Just do things YOUR way. I would suggest a rule where he's not even allowed to talk about it (unless it requires medical attention or something). There's nothing more annoying than listening to a boy complain about how horny they are when they asked to be locked up, so ban it from the start. Pretend it doesn't even exist. Only let him out when you want it, not when he wants to. Maybe try a double-or-nothing rule, where if he brings it up after a week in chastity, he gets another week before you'll even consider letting him out. This will stop it from becoming the sole focus of your relationship. HE'll be thinking about it all the time, but you don't have to!
He should know and accept that making out with you won't necessarily come to a conclusion for him. It's quite okay for you to roll over and say "Thanks for that. Goodnight!" That's his problem.
Think about the things you want to improve in your relationship... maybe it's more foreplay for you, or maybe he needs to cook more often or something like that. He'll soon be on his best behaviour! Your partner is getting what he wants out of all this, so it's important that you do too. ;-)
Have fun and remember, it's quite okay to put it in the drawer for a little while if you feel it's becoming too much or otherwise detracting from your relationship. And it's also quite okay for you to say "I think it's about time you put this back on!" after he's had a break.
If you like being dominated, maybe try using Emlalock for keyholding, and set up some fun games like wheel of fortune to determine whether either of you get to play or not. ;-)
