Selina is in the waiting room of the fertility clinic, when she gets turned on and starts touching herself. Girls Out West really does have the best fantasies, a fertile curvy beauty like Selina with those big bearing hips, her hands sliding off her skirt and ripping open her pantyhose.
Hopefully she could realize if she was born into one of these cults that also distrust apostates she probably wouldn't see through them either.
Modest dressing is the best policy here.
If you do end up having sexual relations, she will feel guilty, and it will affect your relationship, you can count on that. I don't want to advocate manipulation but asking questions concerning Joseph's dishonesty about polygamy to his first wife and his marriage of other men's wives and marriage of a 14 year old may prove more fruitful than just saying wow polygamy is messed up.
Ignore the busy-bodies who want to condemn your significant other.
