I know it’s wrong islamically and probably morally

But i can’t help but be turned on by the idea of my wife having and wanting other men purely sexually only. It’s a fantasy maybe because i’ve had experiences with ‘cheating’ but not to the level of having sex it’s just been unfaithful women, and i also confessed this fantasy to the woman i was supposed to marry and she was fine with it and even happy about it. The thought of it all is exciting to me but i also don’t know how i would react if it ACTUALLY happened. I think this is also a reason that I don’t judge a woman (even if she’s a hijabi/niqabi and looks the perfect muslim) if she has a ‘bad’ past. I can look past it and really, I think i want someone that has a ‘slutty’ past and even better if they’re hijabi/niqabi.
