Just Realizing What We Did Was Illegal

I just was looking up online if what we did was illegal and believe it or no it was , only because he was 18 and I was 14. Since he touched me a lot it can count as a lot of things. Even if I excepted it then Its ok if I don't now. I f I really wanted to I could turn him in to the police, but I don't want to I think. Cuz then he will hate me... I don't know what to do. I'm confused. I still am breaking down into tears a lot. Some nights I even cry myself to sleep because he just happens to pop in my mind.
