The typical difference in the two is husband involvement. In a scenario where the husband is cuckolded, or stays home while she goes out and plays, that is typically referred to as a Hotwife. A hotwife is typically the dominant in that relationship. A vixen is where the husband is involved and there's no shaming involved. The husband is typically the dominant and wife is submissive (in their relationship). Of course there's many variations, but that is the typical. My wife and I are stag/vixen. I am always involved and typically do all the screening. She still has final say though.
