I wouldn't be so sure. There's just not enough decent porn for women. For a woman to enjoy cheating, I think there should be a strong emotional connection and desire to be humiliated. Most women get off from humiliation and male dominance, so making a girl beg for your cock while you fuck another woman and berate the beggar would be hot to most women. But yeah, there's not enough reverse NTR games or stories, let alone "normal porn" for women to even develop this fetish, as you need exposure to content to know if it turns you on. In fact, I think that the number of women who would enjoy being NTRed is way more than men, I'd even say that the vast majority of them could be turned on from this with the right guy.
But rather than from a typical netorare they would enjoy humiliation form of cuckolding, just a man cheating on her wouldn't be much of a turn on, after all first: as a woman she has many options, second: if she considers him a high value man she unconsciously accepts that he'll bang other women, third: women generally more averse to emotional cheating than physical, so in romance novels for women you'll often find "reverse ntr" focused on emotions (it's my assumptions which may be wrong) and uncertainty. For a woman she isn't afraid of her man impregnating others, she won't lose anything from it (unlike cuckold raising another guy's children, which is an evolutionary failure), what she's afraid is that another woman will take away his resources and time / attention, and that's harder to translate into sexual fetish.
To summarize: I think most women can enjoy humiliating cuckolding where you compare her to a better woman, make her beg to fuck her, etc. But they won't feel any strong emotions at her high value mate fucking other women. They would feel strong negativity if he's "emotionally / financially cheating", but that's harder to make into a sexual fetish. "Now all my money will go to this other woman, do you feel it, feel the excitement, you poor bitch?" It's hard for me to imagine it being particularly hot...
