I had oral with my friend when i was 11. normal?

When I was 11 I had a really close friend. She wasn't attracted to me sexually but she thought kissing me and stuff like that was a thing that it was fine for close friends to do ( I was attracted to her a bit.). Anyway; I once talked to her about how two girls would have sex and she was open to suggestions. She would have preferred to do it when we were older ( about 16 ) but I was moving house and school in the next year so I talked her into doing it then. (she didn't really mind). I don't have a great memory but I remember it felt AMAZING to do it with her.(she enjoyed it too but I found it a wonderful experience. I was just wondering if this is normal. Please comment to tell me what you think! I appreciate it! (we were both girls by the way)
