Women with cuckold or cheating fantasies...?

I'm wondering... are there any women who have cuckold or cheating fantasies before having a boyfriend/husband with an interest in this sort of thing?

I've seen posts where they seem to have had the idea awakened in them or been gradually turned on to the idea but I've not come across much evidence from experiences with past girlfriends or from looking around online where a woman seems to have the fantasy already. I do wonder if there are any out there...

I guess the reason I wonder is that, after finding myself single again for a couple of months now, it would be interesting to see if there's a female equivalent out there who perhaps has fantasies that fall into that realm. I suspect that's a very long shot but I am curious!
