Is it normal that my friend and i did sexual things?

So a few weeks ago, me and my friend decided to get drunk. We're both girls and both straight. She asked me to give her a hickey, and i did so. She told me she loved it and she lied down and we began dry humping, and we did this for about an hour. She would hump upward towards my thrusts, and she took off her shirt and i gave her hickeys on her tits and we were feeling each other's and she was sliding her fingers up and down my back. When we finished, we spooned, but somehow my hand ended up on her crotch as she lied in front of me and as i drunkenly was rotating my hand on her you-know-what, she was grinding into me. We both woke up the next morning and both cringed at the thought of it, but lately, i can't think of anything that turns me on more than thinking about what i did with her.
