What is it about the topic of sex?

The older I've gotten, the more sex has seemed to dominate the humor, stories, and jokes articulated by my peers. You would think this would be the inverse, but no. What is it about sex? College humor and college social life seems centered around the idea of sex, if not actual sex itself. It's embedded in the humor I hear on a daily basis, and in the jokes even I make.

And it's not just here. It's not like there's something in the water here in LA. I find this to be true for my friends at different colleges and elsewhere. I suppose I can't complain about this observation, because I am a part of the trend. I catch myself following along with the innocent, if you will, dirty jokes. They're innocent because they really don't mean anything or say much about our personal views. It's just simple humor.

Why is everyone so obsessed with sexualized college life? It's a rhetorical question, no need to give me an obvious "duh." I'm aware of the weird psychology behind the sex obsession. It's normal at this stage, especially with new freedom.  And if it's funny, I should just accept it for that. I guess it doesn't have to be that hard. No pun intended.
