Anonymous Story: High School harassment

When I was a freshman in high school, there was a guy that I had a crush on. My friends always told me he was staring at my butt, but that always made me uncomfortable. The first time he grabbed my butt was in PE and he told me that his friends pushed him into me. I convinced myself this was only a mistake. The second time I could hear him loudly talking about how my butt looked so nice and then he grabbed me again. I never did say anything to him about it, and I never told anyone what happened.
