Sure, lots. I guess a lot of these are mishaps rather than accidents, but there's a fair amount in both categories. Falling off the bed, rope burns, bruises, etc. Getting walked in on. Walking in on friends. I also once broke a bed, but it wasn't mine. Blowjobs which go too deep and lead to choking or sputtering. Cum in the eyes. One time I got cut by a rough edge on a flogger when my partner was pretty overzealous, though she did not mean to break the skin. Oh, then there was the time some drunk guy on his way to the stage at a festival staggered through my camp and fell through the side of my tent while I was having sex in it. I (and some of my partners) have also had to tell doctors on multiple occasions that the bruises all over me (them) are consensual sex bruises and not something they need to worry about.
Of course lots of others too, but those are some highlights.
I haven't, surprisingly. There are certainly a few pictures laying around, but no video.
