I made a special version of Chastity Belt Mod v1.2.2 that was compatible with a fairly old version of Aric's Expansion mod and I don't think that version of Aric's mod is available any more.
Basically because both mods modify the same files and functions there is some amount of work needed to be done to get CB mod working with Aric's mod which needs to be redone every time Aric releases an update and was something I wasn't really wanting to do as I don't use Aric's mod myself and I'm not really wanting to put more time into CB mod than I already have as I'm pretty happy where it is right now.
Aric has in the past taken interest in incorporating some of the CB mod into their own mod, but to my knowledge this hasn't happened yet.
As for instructions if you really want to do this yourself, short version is basically you need to have some amount of experience with programming/modding Strive already and basically just update the line numbers in the CB mod to be in the same position as they use to be with the new lines from Aric's mod taken into consideration. When I did this it took me close to an hour, so you're looking at a pretty big chunk of work (and likely far far longer than 1 hour) if you want to do this yourself.
