If you actually believe that women require sex less often than men, you are seriously misinformed and deeply programmed by the patriarchal society you live in. Or you're a troll. Until about 500 years ago women were widely considered to be the far more carnal sex, and men were warned to not to let themselves get polluted with women's baser desires.
But beyond that, there are so many things wrong with what you've said that I hardly know where to begin. First off, hetero women cannot always find willing men that they would actually want to have sex with, as was written about in great detail in the OP.
Secondly, recent research reveals that women tire of monogamy faster than men and crave sexual variety more than men do. One of the main things that shuts down femal libido is being bored by rote sex, and the constraints of being in a monogamous relationship.
The Bored Sex
Women, more than men, tend to feel stultified by long-term exclusivity-despite having been taught that they were…
But Meana discovered that “institutionalization of the relationship, overfamiliarity, and desexualization of roles” in a long-term heterosexual partnership mess with female passion especially—a conclusion that’s consistent with other recent studies.
“Moving In With Your Boyfriend Can Kill Your Sex Drive” was how Newsweek distilled a 2017 study of more than 11,500 British adults aged 16 to 74. It found that for “women only, lack of interest in sex was higher among those in a relationship of over one year in duration,” and that “women living with a partner were more likely to lack interest in sex than those in other relationship categories.”
There are a lot of sex writers on Medium and they are nearly exclusively female. You really ought to check some of them out and learn some about all of the unmet sexual needs of women. My publication, Sensual: An Erotic Life is filled with essays, erotica, and poetry, primarily from women who are hungry for good sex and not always getting those needs met.
The only sensible thing you've said is that jealousy and possessiveness are bullshit.
Women Want Great Sex; Men Want Emotional Bonding
That’s the story I keep hearing from women, despite the cultural narrative to the contrary
“The women I studied went on the [Ashley Madison] site. Created a profile. Checked back in for responses. Vetted candidates. And then met them in person. Then they ‘auditioned’ them. This was a very intentional process,” said researcher, Alicia Walker. They undertook it, they told Walker, because they wanted to find partners. For sex. If the men became too emotionally attached, they broke it off with them and found somebody else.
This is consistent with what I’ve heard from other women on Medium in the past couple of years, women both writing stories to that effect and commenting on those that others have written. Of course, I’ve heard from plenty of women who want both good sex and good relationships as well, but with the exception of a few polyamorous women, those who already have a relationship aren’t looking for another one. If they are looking for something beyond what they have, they are looking for sex.
