Masturbating

Ok so....I'm 16 and have been masturbating since the 1st grade 😕 I always question myself as to how in the hell I knew how to do that at such a young age...Makes me wonder if I was sexually abused when I was younger or something...The idea of this is really starting to eat me up inside...I masturbate *almost* everyday since then...Its almost like a routine tbh..........So like wtf? Thoughts???
