At what point does one becomes a cuckold?

A good question. I would say you become a cuckold once your wife has sex with another man with your knowledge and approval. That makes me a cuckold husband.

I say it's when there is an intention of continuance, not just the first time but when she intends to continue (regardless of level of consent by the husband).

Stop!!! You're both right,,,in the fetish that has become this lifestyle, just about any type of extra curricular activity by the wife constitutes the husband being cucked. Truth be told, any man whos wife has been with another man (with or without her husband's knowledge, whether or not it continues), has cucked him. If you're a religious permister you should really be okay with it, since the most famous cucking ever, was when God cucked Joseph,,,and Joseph raised the offspring like his own mister,,,near as I can tell, to add insult to injury, God didn't even offer to help out, no tuition, no medical, not even a couple of bags of Pampers,,,If God appeared on the Jerry Springer show he'd get heckled off the stage,,,LOL.

Man !!! That is one statement dude! I think let's just stick to us mere mortals for now !

I guess logically the actual point where a guy becomes a cuckold is when he willing lets his wife go in another mans arms ...whether it leads to plain groping or having the other man's cum shot in her pussy notwithstanding ..

But in the most basic instances of a man getting a hard on in his pants while taking his woman on the beach , knowing she is gonna be wearing the smallest of bikinis and would be stared on by hungry eyes ... does that not qualify for himself acknowledging the fact that he indeed is a cuckold? Just curious..
I think with my dick and fuck with my brains :)

Just for the sake of argument,,,I'm an agnostic, I believe in a higher power, but shun ALL organized religion. If there truely is a religion that represents the one true GOD (whatever that religion may be), surely they are a big disappointment to Him, for if He was truely a GOD, He'd never condone all the *******ing done in His name. Christianity teaches us about free will, if that's the case, then man is the origin of all evil. Any religion he comes up with that imposes itself on another, is also inherently evil. Since just about all religions at one time or another have chosen to ******* non-believers of their credo, it goes without saying ALL organized religions have the capability of being evil.

I absolutely love that LOL, i never thought of it that way, well done and well said!
