Girl on girl

HELP ME UNDERSTAND!!👩‍❤️‍👩

Ok so I had have a girlfriend. I'm really new to being gay or whatever anyone may call it and we had had sex..I think. That's the parts that's really confusing me😭🤦🏽‍♀️. She only fingered me but she didn't go down on me. Is that considered sex for a lesbian? I dont know what to call it. Correct me if I'm wrong!

To anyone who may take offense to this I apologize because I'm not trying to be rude but I just don't understand.
