so I got a question for every female fighter so I do mma and I never saw a girl wearing a cup in mma it will be visible for sure from the spandex but on the other side 90% of the female boxers do wear a cup so why is that it's so rare in boxing since it's only hand fight in mma the kicks and the knees could end to the groin area way more than boxing and explanion
