I don't think my girls cheat more than the rest, in the last few weeks and I haven't read everything in depth because I haven't been on the forum for a long time, but I have read @Maija, yourself, @Milou-dH and a cousin of Laura have had to be punished, so although it doesn't mean that it should be tolerated, I think the situation in my house is normal with all the girls.
The intention that they wear the bra on a regular basis is not any punishment, if not that I have realized that it is a degree of protection that, in general, should be the usual. Here in the forum I have read certain things that they can do with their boyfriends... I am not going to go into depth, nor am I going to go crazy about it, but it is clear that one thing is that they take care of their boyfriends, it is something that can not be forbidden, and another that they break the rules, they have to feel protected at all times.
It's something I've talked about with my brothers-in-law and it's something that all three of us agree on.
