I refuse to ride a boy-style bike because it hurts so much.
You guys have a lot of soft tissue and nerves to deal with down there. We have a lot of nerves, very little to cushion, and then BONE. So when the nerves hit the bone it feels like a hammer hitting your baby toe.
You want to faint. So, I try to keep that part away from harm. See how nice this is with a bent bar? That gives me room to put my feet down on the ground if I need to and not get smacked one in the crotch bone. Or the pubic bone, or the pubic symphysis.
I don't engage in physical violence, but have had a few unfortunate accidents. It's not pleasant. Luckily, our stuff is a bit more protected than yours.
