Boy assaulted

This happened 2 years ago but I’m still a bit bitter about it. One time at PE after running for a bit we started walking in loops, while I was going ➡️she was going⬅️ and at the point where we met she extended her hand and touched my penis, then she laughed and went on with her walking. After class I told the teacher, the second the girl got called she started crying and screaming, and the female teacher defended her and believed that it was an accident. Not to mention before this I constantly catch the girl looking at me down there. Anyways I hope she doesn’t do this to people anymore. Edit: the amount of people saying I’m a snitch and I should enjoy it is upsetting
