Anonymous Story: I was assaulted

This story may not be as serious and as painful as the others. It may even seem negligible but it bothers me a lot. I was 14, almost 15 years old. It was a class trip, nothing too special, just a bunch of teenagers wandering around in a big group. It was fun, it was interesting, everything seemed just fine. We were by the sea, having some free time. I was with my friend, we were just walking around, talking about something and then a boy, who was my classmate, came. He clearly demanded for some attention and when he didn’t get it, he started to touch me. Touch me everywhere, touch me inappropriately. It was disgusting. My friend and I tried to stop him, I tried to push him away but he wouldn’t stop. He thought it was just a joke. He thought that if he was physically stronger than us, he could do anything he wants. I had never felt so bad, I had never felt so humiliated. I had never felt so dirty. Then he stopped, he laughed and went away. Nothing happened afterwards. I tried to act like I am fine. I haven’t told anybody, even my teacher. I believe that my friend has already forgotten it too. I just kept it inside me and now four years have passed. I’m stronger, I’m happier but I can still remember everything so clearly and it just kills me.
