My youngest sister wrestled throughout highschool. At first we were all worried about the closeness of the contact but once we went to the matches it was clear that the boys were just worried about winning. Yes, there were some unfair calls from refs. There were boys who forfeited and refused to wrestle her, but for the most part it was a positive experience for her. She did it for four years and was captain for her junior and senior year. During the off season she also did wrestling with the USGWA (U.S. Girls Wrestling Association) and she was nationally ranked with them. She was also a youth wrestling coach and the team she coached was comprised of about 30% Girls.
If you are worried about your daughter being teased, it certainly wasn't the case with my sister. She was elected as a class officer and she was homecomming queen! She said the only thing she didn't like about it was that they always announced the winners over the PA at school by weightclass so every time she won a match, they'd announce her weight to the whole school!
