Is it normal that a girl fell asleep while i was fingering her?

So me and this girl got were making out in the bathroom at this party got mostly naked. She said she needed a condom didn't have one so I finger banged her. She was making porn noises but I think it was fake and eventually we stopped and went back to the party. That night I was sleeping over and she was like "'do' me daddy" (she says stuff like that I guess) but I remembered the condom thing so decided to try again with the hand. Anyways she made the noises again but this time she stopped and when I looked up she was snoring. So I stopped. Am I doing something wrong? Is it just not very effective for anyone?
