Human females exist mainly to:
>extract resources and redirect them back to society and its leaders (the "psychopaths" or "alpha males") as a light form of bio communism and a taxation system that prevents beta males from hoarding everything they produce
>blue ball beta males to inflate the allure of sex and thus increase supply artificially, e.g. by dressing like sexual degenerates (yoga pants, super tight gym shorts, sexy lingerie as outerwear, thongs at the beach), by flirting, by refusing to have sex ("I have a headache"), through mannerisms and subtle body movements and posture (hip swaying, wearing high heels to accentuate her curves)
>offer sexual rewards for being a good boy or an alpha male
>manipulate everyone around them, they create noise that confuses people, they nag, they exhaust you mentally to make you weak
>they make beta males infight to weaken beta males, encourage competition and accelerate evolution
>they act as a hivemind: the pussy cartel controls the sexual market according to the female's programming (VERY IMPORTANT, if you don't get this you'll mistakenly think that society is a matriarchy and that females decide these things themselves!)
>they get pregnant and create new humans (workers, leaders, females, etc.)
>provide aesthetic value to the group by simply looking good, youthful, etc. (see pic, every culture on earth has worshipped pussy as one of their gods and pussy is lifefuel, literally and figuratively)

And more importantly, as females are very gregarious, extroverted and collectivist, acting as a hivemind:
>every aspect of the female personality can be reprogrammed, including her sexuality, ick instinct, consumerist desires, whom she socializes with, whom she blue balls, whom she fucks
>the leaders of society can reprogram women as an army and use them to control the horde of beta males
Thus females work as a carrot-on-a-stick mechanism in our species.
