I liked the article for the most part. It's always good to hear an experienced woman's input on the topic.
I don't know who Dan Savage is, but I didn't necessarily agree with his statement, "It's not cuckolding if there isn't an element of humiliation, degradation, or denial."
I'm a purist when it comes to the term "cuckold" because of what mainstream porn has done to the genre. They destroyed it. So a cuckold is purely defined as a man with a wife who has sex with other men.
To me, those three things are branches of the BDSM tree that are often associated with cuckolding.
Had he said, "Cuckolding often incorporates blah blah and blah", then I would have agreed.
