I thought you made a few sensible points in your post even if I did disagree with some. For example, your closing sentence sounds very sincere and reasonable:
"Sex requires communication if you are unfamiliar with each other's likes and dislikes. More importantly, porn stars are really good at sex. Either that or they are very cleverly edited."
But if that was also a joke, well fair enough but I'm not going to be too hard on myself for not picking up on it.
