Molested or child curiosity?

When I was around 6 I think a boy who lived down the street touched me regularly. I think he was 9 or 10 so I'm not sure he knew what he was doing. But he also locked me in rooms and barricaded the door as I screamed and tried to get out and he wouldn't let me. One time I remember his parents had a trailer/camper in their driveway and we went inside to play and he wouldn't let me out because he told me if I left the sweat bees outside would sting me because I was clearly sweating and he touched me there too. We were both young but I feel like he had to know it was wrong and I know I didn't want it. It still effects me and I have some pretty strong flashbacks. I don't really know what to think about it though
