Why do guys keep getting erections around my little sister?

Anonymous
So as summer arrives, I visited my sisters school ( she's now a seventh grader) I saw that during her gym class she wore spandex and knee high boots ( that's just what she does) but for some reason while they were running there was a bunch of boys following her and stoping to do what looked like the waistband trick and then kept going. I pulled her aside and told her what happened and she told me that she saw them tucking their waistbands often but she never knew what for. what should I do?
It's her fault
I need to intervene
