I know several women who have not a feminine sport. For example, the daughter of Muhammad Ali - Laila Ali - a professional boxer, she spent 24 professional fight and won all 24 of battle. It is the world champion in women's boxing or Patty Moise, she participates in NASCAR racing, although race is not considered a female sport.
