They say that men are mostly visual in their sexuality whereas a woman's erotic fantasies are much more internalized. In a way that's true, show a guy boobs and/or ass and he'll start salivating 9 out of 10 times. Show a girl a cock and the best you can hope for is a giggle, maybe a blush if its a monster dong. I'm somewhere in the middle. I enjoy seeing big tits and big dicks, but I also like things covered up a little, hidden from view. That's why I like cleavage for example. Not showing stuff (at least for a little while) is sometimes the biggest turn on. Probably because you know the good stuff is there - or like in this clip "happening" - but you're not quite able to see it yet.
