Childhood incident

When I was about 10 I was on the couch with an uncle, and I thought things were great, like a normal uncle-niece relationship but one day he stuck his hands down my pants and started to suck on my toe and I didn't know what was going on I tried to get up and leave from the couch but he wouldn't let me and I didn't think much of it but I wanted to leave but he wouldn't let me. He told me "shh" and to not tell my mom. The uncle would always be very "friendly" toward me, but I was 10, I didn't know. I remember watching videos about safe and unsafe touches in elementary and that's when it clicked and I wanted to tell my mom. It took me a while to tell because some kids would laugh about the video and I didn't want to be made fun of but I did feel pretty bad. It wasn't until a year later or so when I did and she told my dad and my dead started to threaten him and I was pretty scared. I don't think about it much but when I do, it makes me feel like a piece of my innocence was taken away from me so early on and it makes me feel pretty low. Is that wrong or am I just making a big deal out of things. I'm 17 now.
