@Grewd I don't know of any man outside of cucks that doesn't wan't more variety when it comes to sexual partners, it is an evolved drive in us all. I can understand the swinger thing. The guy also gets extra action and the variety men desire and it is open and honest with no deception. I don't doubt that the cucks get off on this, I just don't think it is psychologically normal. These guys often times don't just have their wives banged by other men, they also wear cages on their ****s that prevent them from being able to jerk off so that the wives can control their sexual release. They also perform sex acts on the bulls. That doesn't sound to me like a healthy man.
Doesn't sound directly unhealthy either as long as it's consensual, which it ultimately is. They can take their power at any moment they want, but they simply don't want that. I can't disagree with this not being normal, it certainly isn't normal, I don't have an issue with other people doing bizarre stuff.
I'd say this sort of arrangement is very honest. The apparent deception is a part of the game, so technically it isn't really deception. I'd argue that it requires greater level of trust than ordinary relationship, there's a much much higher risk she could branch swing.
If any man turns into a cuckold primarily to keep his wife, then sure I do agree it's not healthy mainly because he doesn't genuinely want that. For a true cuckold this doesn't appear to be the case, their motivation is entirely different.
Many men enjoy playing submissive roles, a cuck is just on the extreme end of it. Evidently that evolved drive you talk about isn't in everyone.
If they want to do this I'll leave them to it, even though it's not for me though.
