She could realistically enter a wrestling tournament just like that. That’s all the protection her body needs.
With guys, it’s different. They have to wear a cup. Without it, they’d lose every match. Isn’t that sad? Guys need artificial protection just to participate in a basic sport.
I’m imagining her using her crotch to pin someone’s leg or arm. She can use it as a grappling tool because it doesn’t hurt her.
