I am in middle school and today me and one of my friends who is a girl were playing beach volleyball by?

ourselves and we were trying to get it up on the top of the bleachers in the gym because they are stacked bleachers because there were know basketball or volleyball games so its cool to climb up. well our volleyball fell up there and we went to ask our PE teacher if we can climb up their and get it and he said no to us and he asked a guy from our pe cl to go up and get it. We asked him why we couldnt go up but you let him go up. he said if he fell down it wouldnt matter but if either of you fell down off the bleachers i would be devistated. what do you think is my gym teacher being genderist or does he really care about us girls?
