With all the talk about legalizing gay marriage and decriminalizing marijuana, we started thinking about the super-important stuff that we wish the po-po would come in and regulate. After the jump, 30 unacknowledged crimes that should be illegal.

This weekend I had dinner with a friend of mine who's having a bit of a problem with some friends. Two of her pals have started dating and are so, so, so in love and make sure everyone knows it by making out, snuggling, and pawing each other in public constantly. It's making everyone around them deeply uncomfortable, though, on the whole, my friend is very pleased that they're dating. She's not sure how to handle it, as it's not easy to say to a friend, "Your constant necking in front of me is grossing me out." So, she's taken to avoiding them, unless there are a lot of other people around. But it got me thinking -- how much is too much PDA? I'm dating someone new and we smooch in public, though not in front of friends, and I feel fine about it. What do you think -- when does PDA cross a line?

Are you into public PDA ... specifically of the horizontal polka variety? According to Don Q’s Lady Data, 12 percent of women are down with having sex in public. A risky rendezvous no doubt. Whether you are part of the 88 percent that prefers to keep your sex life in the bedroom or a member of the public freaks club, you can’t help but enjoy these naughty episodes. After the jump, some tales of sex in public places. Share yours, if you dare!

I was at brunch with my girlfriends this past weekend when we spotted a beautiful, newly-in-love couple. They were sitting across from each other holding hands and staring adoringly into each other’s eyes. He leaned over and whispered something into her ear … she giggled and scooted closer. His hands started wandering … she tilted her face in; before we could swallow our Eggs Benedict, they were swapping saliva and grabbing each other’s unmentionables. I felt like I was watching a particularly graphic and bloody open-heart surgery on “Grey’s Anatomy.”

Since we don’t spend most of our days in bed, we can’t expect all romance to happen there. As an article from Match.com’s Happen magazine suggests, you and your partner can seduce each other while going about your daily activities. However, we don’t recommend their tips for kicking things up a notch while in public. Instead, read our five moves for turning up the temperature while you and your honey remain clothed.

I’m sure you all are familiar with the insane amount of “I Heart My Boyfriend” clothing and other items that are sold on the back pages of tabloid magazines. And I’m sure I’m not alone when I say, “I really hate those things!” My rant continues after the jump.

Several times over the past couple weeks, I’ve ridden the subway with a couple that kisses very loudly while they ride the train to work. I’ve had to stand next to them, inches away, while they “smack,” “smack,” “smack”-ed each other’s lips over and over again. They must have kissed 15 times in the time the train traveled one stop. This morning, I just about had it. I was so close to telling the kissing couple they were being inconsiderate and making others uncomfortable—I can even hear the sound of them kissing when I’m listening to my iPod. I held back, though I’m not sure I can much longer. From now on, I will be getting into a different car if I see them hopping on the subway with me. After the jump, what’s not allowed when it comes to PDA.

Campaigning for the upcoming presidential election is winding down, but we thought you might like to revisit some tender moments the Obamas had while visiting state after state after state. Do you think they’ve had sex in all 50 yet?

If the cute photos of the Obamas smooching weren’t enough political PDA for you, check out this slideshow of the Bidens’ greatest moments. [Huffington Post]

With all the hullabaloo over Barack and Michelle Obama’s much watched fist-bump on Tuesday, we started thinking about how it compared to other political public displays of affection. Who could forget the never-ending kiss at the Democratic National Convention between Al and Tipper Gore? Some people are still holding back their lunch. Republican Presidential nominee John McCain has a PDA pattern of his own—at every rally he make sure to thank wife, Cindy, then gives her a polite kiss on the cheek. For others, as well as another photo of that fist-bump (we couldn’t resist), click after the jump…

Don’t they just make you want to barf? They look like they want to devour each other in a fit of lust.

People who make out excessively in public places annoy me, so when this couple had a tongue-fest in a Shanghai subway station and the security video of all the action was released on YouTube, I couldn’t help but laugh to myself. I feel a little cruel since the guy quit his job because he’s gotten harassed so much about it, but really, he should own his performance and deal. [YouTube and All Headline News]
