I'm not sure if I was raped

Okay I might be overreacting to this but I've been thinking of things that happened in my childhood and i remember a thing that was sort of pushed into the back of my mind. When I was 7 I went to a McDonald's with my dad and my brothers and as you do when your a kid you go to the playplace for a bit then you eat your food...but that time was a little different. There was this girl who looked to be around the same age as me and she came closer to me and touched my crouch and my genitals. now that am thinking about this I'm not sure if I was truly sa'd or if I'm just overthinking something that happened years ago.
