This is just a rant, I understand there’s nothing anyone can do. Men in relationships never have to worry about their woman being aroused by other men. Meanwhile they are getting spontaneously aroused by other women often. I know erections are autonomic responses but so is jealousy. It makes sense for women to be hurt about their partner feeling sexual energy with other women. It’s so unfair that any male partner can never be as loyal to me as I can be to him.
