The Female Version of a Nice Guy is the Nice Girl. Now a "Nice" Guy is a guy who either pretends to or tries to be Nice to someone not out of genuine good will and kindness ,but purely so he can get sex from a woman. Whereupon he'll stop being respectful to her and likely leave her. He expects sex from her in exchange for being nice and when he doesn't he gets offended and angry.

The nice guy is hated because he's not really a nice guy and is only being nice in order to get sex from a woman. Our culture actively hates these kinds of men and views them as manipulative ,creepy ,pathetic et cetera.

There is the female version which is a Nice Girl. But its not a girl who pretends to be nice in order to get sex. Its a Woman ,usually in a relationship, who has sex or pretends to like sex in order to reap the relationships benefits.

Its the kind of woman who'll have sex with her partner "Eagerly" for years but once they get married she instantly stops. Because she never really liked the sex and only did it just to get a Ring and Marriage. And once she has done it she stops knowing her partner now can't leave her.

Its also why you see a lot of woman fake their orgasm. Because they don't actually find their partner sexually attractive but want the relationship benefits so they pretend to enjoy having sex with them. Its the equivalent of a guy who pretends to agree with the same politics as a woman so he can get in her pants. Yet somehow society views the former as a poor oppressed victim yet the latter as an asshole. Even though both people are lying in order to get what they want.

This is why you see a lot of men complaining about Dead Bedrooms. This is why you see women talk about faking their orgasm's or viewing sex as a chore. This is why the meme of sex drying after marriage occurs. Because there is a noticeable amount of women who are "Nice Girls". Women who pretend to enjoy sex ,even when they don't want to, because they want to keep being in a relationship with a man and reap the benefits. And once they do the sex dries up.

Most interestingly Society views these Nice Girls as poor victims who are "pressured" or have sex due to societal expectations around women. How they feel they "Have" to service their partner because they're "Scared" of losing the relationship and being single. Yet nobody here views nice guys as poor victims who were raised to believe that being nice to a woman was a way to get sex. Its astonishing the double standard. If your partner is not forcing or coercing you into sex you are not a victim and nobody is making you do it.

I believe men need to avoid and stay away from "Nice Girls" like how Women need to stay away and avoid "Nice Guys".
