OnlyPorn, the world's 789th largest porn website, has decided to ban the use of electric fans on set for their OnlyPorn Originals in-house projects, stating that fans on the "high" setting can change the trajectory of cum shots. I agree that stray cum shots are a problem, but the actors need to keep cool. I hope the air conditioning is good.
In Korea, people commonly believe that fans will kill you if you leave them on for too long. You should have linked this to that.
