first, you might wish to learn the difference between hotwife and cuckolding. I used to think they were the same as well, but they are not (even though they share one component).
Look up terms like compersion, hotwife an/or stag/vixen relationships, and cuckolding. There's some very big differences in some of them. Tons of good youtube videos and podcasts on the subject.
That way you'll know which interests you more, and have a better result in your search and adventure seeking.
