Suzanne Hello and welcome. I hope you get something valuable from discussions here. From our side, I think its good to have another keyholder speaking on the forum.
I'd like to ask what belts your father, husband and brother wear and whether the restriction on their sexual freedom has, or is intended to have, any overall submissive effect on them?
I've also been looking at what @JackF wrote about the rules agreed from the first date...
1) Chastity isn't a game it's a lifestyle.
2) Don't complain, but bear it.
3) Accept that the chastity belt is inextricably linked in our current and future relationship.
4) Acceptance makes it easier for you.
These seem very strong, and since they're agreed at the outset with consent, I've no problem with them. In fact item 2 is something that I myself need to embrace. Are there any other rules in regard to chastity in your house?
