Yes, my girls certainly have brothers.

Last week I was outside with Rozzy as she attempted to ride her tricycle. She was trying so hard to pedal. The poor girl has short legs, so this is a little difficult for her. I pushed her along to help her get the feel for it. Then I decided to just give her an extra hard push and let it go for a little bit. She soon went off the path and the tricycle tipped over, dumping her off.
She immediately started laughing and grabbed her crotch shouting, "My beh-wees! My beh-wees!(=Rozzy for berries)"
I laughed so hard!! Yes, my girls certainly have brothers.
