How does what work?? They changed in the girls locker room, did the wrestling practice, changed back.
As far as the actual wrestling, they were treated like one of the guys. Assigned a weight class they had to make, assigned matches with someone else in the weight class, did the match.
If you mean like, "Zomg he groped me!!1" sort of issues, on the mat they were treated like one of the guys and no one made a big deal out of it. Came with the territory and I just assume they realized that before deciding to join the wrestling team? Dunno.
