first. have done before when I was high and Ricky Gervais stand up was on in the background. The one where he talks about Humpty Dumpty, lol. Still makes me laugh now.
There was 1 chick who used to go cross-eyed when I f**ked her, was so funny I burst out laughing frequently. Despite it being kinda hawt in a weird way I couldn't keep a straight face.
She got hella embarrassed about it and must've been trying really hard not to do it afterwards cause her eyes would roll into the back of her head instead (also kinda hawt imo)
i do it all the time, i lost my virginity with Curb Your Enthusiasm on in the background for instance..laughed probably more than once, bit the sex was still pretty good...pretty, pretty..pretty good
