It's a "law of nature"; throughout the animal kingdom -- insects, fish, birds, mammals -- the males compete in various ways to determine dominance & the right to select the best female for breeding. Humans are no different but that the competition is civilized. (We rarely fight to the death for the opportunity to impregnate a female). It's been this way since prehistoric times ... 'til the feminist movement of the 1960s, anyway. With sexually aggressive females comes emasculated males -- guys who have no idea how to properly hit-on or seduce a woman. Hey, if chasing wimpy guys works for you ..... or, are you a wimpy ball-less guy that wants women to chase you?
