PDA vs PDI

I had to put my iPod on because I wasn't enjoying the sloppy sounds of making out accompanied by light moaning going on behind me...

Don't get me wrong! Hold my hand, give me a kiss, playfully swat me on the ass... (lol) I'm a fan of PDA, but when it becomes a Public Display of Intimacy it's just a leeeetle too much for me. Time and place people, time and place!
