Labels are cute, but at the end of the day this isn’t a zoo, it’s your sex life. Bulls, stags, vixens, cucks — they’re just shorthand for fantasies that can look a hundred different ways once you’re actually in the room.
So try the labels on, keep what fits, toss what doesn’t. The hottest part of the lifestyle isn’t the terminology; it’s the two (or three… or four) of you deciding what turns you on and then actually doing it. That’s the magic.
