I hate the portrayal of athletic women as overly masculine

Even in a show like Glee, where they show Coach Beiste to identify and act in a feminine way, all of the jokes at her expense have something to do with her being “manly” or “butch”. Why do female athletes have to either overly sexualize themselves or accept the title of “Man-Ish”? Why can’t they just be WOMEN? Or maybe even PEOPLE?
