Falling asleep
Neither of these were personally awful, but I think from an objective point of view any sex where you fall asleep is bad sex.

1) We were both very tired, very drunk, but went for it anyway. I woke up maybe an hour later still on top and inside. I woke her up, feeling guilty. "Was it okay?" I asked, expecting the worst. She smiled and said "Great" and went back to sleep. As far as I can tell, we spontaneously fell asleep.

2) Lately I've had blackout problems as I drink. On Saturdays I drink a ton and get home safely with gaps missing in the details. I woke up next to my woman in the morning and went down for the first piss of the day. I sat down on the toilet (too lazy to stand) and began to evacuate my bladder. There was a wet sensation, like my knob was dangling in the water. Disgusted, I jumped up, expecting to see the bowl overflowing with christ knows what. Nope, it was clean. I was wearing a condom which was ballooning up with urine. I asked the woman and apparently we got into it but she was tired and had enough, so she asked me to stop. A second later she turned to me, expecting me to be angry, but I was fast asleep. The condom was never taken off. I'm impressed I was able to perform well enough for her, but still disturbed I have absolutely no memory to this day of it happening.
