Guys: Girl tackles you during gym class in tackle games?

So in gym we played tackle handball right? And Im light weight but not short. I also am on the wrestling team s I was totally game to play the teams fav in class today. But as always the guys kinda go wtf? when I tackled them, even though most know I wrestle and I was wearing my provincial shirt which the sub pointed out and aksed how well I had done.But the guys laugh or r suprised when I tackle nd get dirty their were only 3 other girls playing so ya the class is mostly guys but still. I need help dealing with them because it's like this whenever I am intense in sports in gym and it's only day 2. Guys whats your opinion on being tackled by a chick? BTW this game is played on wrestling mats on your knees sadly not standing
