I suppose so. I imagine it is associated with letting another man "supposedly more masculine" enjoy the pleasures that your wife or girlfriend can give him just like you have experienced with her?I should add that the intense eroticism of the humiliation and emasculation I've experienced is hard to explain, and hard for most people to understand, but if you've been there you know.
And her letting you know he was "better than you" and further did things to each other that you don't do together.
What was the turning point from angry husband discovering your wife was having an affair to the "intense eroticism" you say.
