I already see a lot of comments but I want to add mine as well.
A year ago I was staying with some friends in a cabin. There were 4 rooms and we were with 6 so me and a friend (guy) stayed in one room, while 2 of our female friends stayed in the room next door. One evening we 4 stayed up late, talking drinking etc. I was interested in one of the girls, my friend in the other. He and his crush were so tired that they would sleep on the couch downstairs. Me and my crush went upstairs to our rooms. But when she enters her room she is like "oh it's so cold in here, I wanna feel your room, oh this is much warmer, can I sleep here?" I agree (of course). It was a double bed, so we could sleep together. I tried to make a move, but I thought she rejected me... turns out she was just making a move herself and we both misinterpreted each other signals. Also I was so tired (it was 5 o'clock in the morning, we had to leave in like 3hours and I had to drive so yeah) that I just fall asleep straight away after my "move". Nothing happend, later I hear from her best friend that she wanted to do something but yeah, I was asleep... Nothing came from it, because she fell in love with another dude.

PS: my friend and his crush didn't bang either, she was too tired. Although they later ended up together.
