confused and horny??

one of my girl friend’s is always really touchy with everyone when she’s drunk and I think I’m actually really attracted to her. she’s kissed her girl friends before when she’s drunk so one time when I was really drunk I decided to go for it and kissed her since she was being flirty. She pulled away and then I had to kiss my other girl friends to cover it up. another time, when it was just us we were kinda drunk and she started to unbutton my pants but I was still confused from the last time so I didn’t do anything back so it ended there. I really would like to experiment with her but I don’t want to ruin our friendship. She’s also the first girl I’ve ever been attracted to in real life usually its just porn and Im always into men
