Did I perform COCSA or was it just curiosity?

Hi, I dont know if, as a child, I performed COCSA on my far cousin or if it was just natural children curiosity. Im four years older than her and when this happened i think i was around 9 or 10, I dont really remember. I remember one summer I hit my knee with a rock and that have me a scar and I even hit my clitoris. I thought it was broken because it had a slit. I dont remember if this was the same summer or the next one but i remember always thinking my clit was broken and i remember playing families with her and her older brother who is 2 years younger than me. I would want a sneek of what her vagina looked like just to see if it looked like mine so when we were playing she was my child and i would do the movements as if i had to change her undies, so i just pulled them down, did the mimick of cleaning and pulling them back up. She never said no and i never touched her but i dont know it this is abusive behaviour or just normal curiosity bc i felt shame to tell my parents that i thought my clit was broken. I feel a lot of shame and i plan on telling this to my therapist but for now i dont know who to tell it.
