Women subconsciously understand women are natural whores. For a man to somehow not get any poon repulses women on a visceral level: This man is an evolutionary dead end and his genetics deserve extinction.
That may be partly it, the main reason is woman understand they can use sex to manipulate men (not even "subconsciously" it's completely deliberate). For them to be able to manipulate men with this method, they need to men to greatly value sex. One way they do this is creating a culture when men are entirely valued by their ability to achieve sex with women. "Incel" is an insult used to reinforce this culture.
