TW! was i sexually assualted?

When I was 6 maybe younger my cousin who is three years older than me exposed me to porn. Like we’d watch it together and at the time I didn’t have a clue what it was and she’d dry hump me or we’d both just hump the floor.. I know this is weird and I know it’s “normal” for kids to explore stuff like that and I don’t blame her at all because now I know it was because there was stuff going on in her home.

I don’t think it was sexual assault because we were both young and I don’t necessarily think it was for her pleasure I think she was just trying to figure out what had happened to her at home.. idk??
