Is there anyone in the nation's capital busier than President Obama? Hardly. Which makes it amazing that amid all of the demands of the nation's highest office, President Obama has actually, and rather surprisingly, emerged as quite the ladies man. So, for Valentine's Day, we're making a close examination of perhaps the most under-analyzed aspect of his presidency to date: His flair for giving a kiss.

President Obama is roundly celebrated for his deft speaking abilities, but we've noticed he has mastered a whole other art of lip service, too. And the proof of his mastery has been captured countless times with photos of the president getting cozy with a host of political figures and world leaders.

As you look through these photographs, take note of the president's signature kissing technique, as it reveals a whole new dimension of his persona. President Obama, typically the picture of calm and poise, throws caution to the wind and lets his lips fall where they may, much to the delight of those on the receiving end.

For starters, take the president's embrace with House Minority Leader Nancy Pelosi at the National Prayer Breakfast earlier this month, an encounter in which he pressed his lips dangerously close to her grinning mouth -- a captivating sight to be sure.
