Withholding sex can be a mechanism of domination and control by women, especially towards weak men.

Literally anything that at least one of the partners likes can become an element of blackmail, teasing and bullying (for example, during infidelity). Part of the power game can even be love to home baking, when one of the partners intentionally does not cook for the other as an "element of punishment", no matter how stupid it is.

Well, why the term "withholding sex" is most often applied to women is very simple... In terms of the desire to have sex - the decisive and final word of consent is for the woman. Sex in a sense is a "service" from women to men. But not exactly in terms of a transaction, but in terms of consent. Since women (on average) are much weaker than men physically, it makes sense for the consent of a woman in a sense to have more weight, because she is physically threatened more. And a normal man will also put the woman's consent and her comfort first, which gives women more power in this regard.
