If there’s one thing that we see rarely — if at all — in porn, it’s laughter. What strikes me about most pornography is that it’s always so deadly serious. A nervous giggle is permissible in a few instances (such as those ghastly “casting couch” videos that are evidently ubiquitous, in which “innocent newcomers” are interviewed and then fucked for the first time on camera.) But laughter during sex, a shared joyful recognition that getting naked and sweaty and contorted is frequently hilarious? Nope. For too many, porn reinforces the obligation to perform, which creates anxiety, which creates in turn a deathly humorlessness.
