Implicit in sexual fantasies is the underlying wrong view that the actions in the sexual fantasy are not harmful & will bring happiness to both sides. The Dhamma states in many places that sexual liberalism or sexual promiscuity harms, defiles & degrades women.
Unchastity/misconduct taints a woman.
Dhammapada 242; AN 8.15
And how, householders, does a wretch live together with a wretch? Here, the husband is one who destroys life, takes what is not given,
engages in sexual misconduct, speaks falsely, and indulges in liquor,
wine, and intoxicants, the basis for heedlessness; he is immoral, of
bad character; he dwells at home with a heart obsessed by the stain of
miserliness; he insults and reviles ascetics and brahmins. And his
wife is also one who destroys life, takes what is not given,
engages in sexual misconduct, speaks falsely, and indulges in liquor,
wine, and intoxicants, the basis for heedlessness; he is immoral, of
bad character; he dwells at home with a heart obsessed by the stain of
miserliness; he insults and reviles ascetics and brahmins. It is in such a way that a wretch lives together with a
wretch.
AN 4.53
There are, young householder, these six evil consequences in associating with evil companions, namely: any gambler, any
libertine, any drunkard, any swindler, any cheat, any rowdy is his
friend and companion
DN 31
And as I remained thus heedful, ardent & resolute, thinking imbued with sensuality arose in me. I discerned that 'Thinking imbued with
sensuality has arisen in me; and that leads to my own affliction or to
the affliction of others or to the affliction of both. It obstructs
discernment, promotes vexation, & does not lead to Nirvana...I foresaw
in unskillful qualities drawbacks, degradation & defilement, and I
foresaw in skillful qualities rewards related to renunciation &
promoting cleansing.
MN 19
The Dhamma also teaches the goal of a woman is to have a husband, to not share a husband with another woman, to dominate the relationship & that sons are her support in life.
A man is a woman’s aim, her quest is for adornments, her mainstay is sons, her desire is to be without a co-wife and her ideal is
domination.
AN 6.52
This is why sexual fantasies are 'misogynistic' according to the Dhamma because they are based on the intention to harm women rather than the intention to have metta (loving-kindness) for women; and they are based in making a woman submissive to the desires of men rather than giving authority/dominance to the woman in a male/female relationship.
A wife is ministered to by a husband by handing over authority to her...
DN 31
Misogyny (/mɪˈsɒdʒɪni/) is the hatred of, contempt for or prejudice against women or girls. Misogyny can be manifested in numerous ways,
including social exclusion, sex discrimination, hostility,
androcentrism, patriarchy, male privilege, belittling of women,
violence against women and sexual objectification. Wikipedia
For thousands of years, women have been forced to serve as concubines, mistresses, prostitutes & sex slaves for men. This has probably not occurred because men intrinsically want to oppress women. It probably occurs because men are generally so ignorant, so blind & so heartless that they cannot see the intrinsic harm of the sexual exploitation.
Sexual fantasies are similar. In sexual fantasies, the man views his actions towards the woman that is the object of the fantasy is intrinsically harmless, when it is not. Sexual fantasies are misogynistic sexual objectification.
Since the sexual revolution of the 1960s, much harm has come to women. For example, the 2nd wave feminism that arose concurrent to the sexual revolution promoted complete sexual liberalism for women. However, due to the consequences of this, the 3rd wave of feminism became divided over the sexual liberalism promoted by 2nd wave feminism.
Unlike the determined position of second-wave feminists about women in pornography, sex work, and prostitution, third-wave feminists
were rather ambiguous and divided about these themes (feminist sex
wars). While some thought these sexual acts were degrading and
oppressing women, others saw it as empowering that women were owning
their sexuality.

The following articles describe the 'dukkha' that impulsive heedless sex has brought to women, which are similar to the 'hungry ghost' & 'hell' worlds of sensuality described in the Potaliya Sutta.

Or read about the lives of the world's most famous sex symbols, how many sexual relationships & sexual affairs they had and what it brought them:
Monroe's troubled private life received much attention. She struggled with substance abuse, depression, and anxiety. She had two highly
publicized marriages, to retired baseball star Joe DiMaggio and
playwright Arthur Miller, both of which ended in divorce. She died at
the age of 36 on August 5, 1962, from an overdose of barbiturates at
her home in Los Angeles.
Marilyn Monroe
In 1974, Bardot appeared in a nude photo shoot in Playboy magazine, which celebrated her 40th birthday. On 28 September 1983, her 49th
birthday, Bardot took an overdose of sleeping pills or tranquilizers
with red wine. She had to be rushed to hospital, where her life was
saved after a stomach pump was used to evacuate the pills from her
body.
Brigitte Bardot
In conclusion, returning to the Dhamma method of viewing women as 'mothers, sisters & daughters', for a woman to be a good mother, it is best she has a good mind. Women engaging in heedless sex does not contribute to a good mind for motherhood. This is a reason why the Buddhist looks upon women like mothers. Mothers love their family & want a strong stable family. Women engaging in heedless sex does not contribute to good families and a woman's true happiness. The Buddha explained this respect for mothers in the Lokapala Sutta.
