Labels are labels, it really doesn't matter in the end. Like I've said elsewhere, for me sharing is just a fantasy anyway not something I want to experience. But that being said, if somebody I knew were doing it and was pulling constant 10's on the side while their girlfriend/wife had her own experiences... I'd have a hard time thinking of them in my opinion as a cuck. But that's the thing about labels as said above, society applies them and obviously everyone's different. Ultimately, it's a porn game... don't overthink it. And if somebody is swinging/sharing and getting access to the girls Anon does (or other MC's in somewhat similar titles) I feel like they themselves would not be feeling insecure about what others would be saying of them.
So everyone just chill and enjoy
