Sex sells..
"Says who? Just so you know, the people who talk that way think that monkeys can do this. They take all this monkey crap and just stick it in a briefcase completely unaware that their success depends on something more than their shoeshine. YOU are the product. You- FEELING something. That's what sells. Not them. Not sex. They can't do what we do, and they hate us for it."
-Donald Draper.
Do you live on the moon ? Sex sells. It has always been so and always will be.
Yeah, that's why every ad has a naked girl on it and every porn wins an oscar. Emotions sell, that emotion might be sex every once in a while, but if you actually think "horny" is the be all and end all of emotions you're delusional.
