How to kiss my boyfriend without it being awkward?

My boyfriend and my close friends are coming over tomorrow to hang out and watch a movie. How could I kiss my boyfriend (it will be our first kiss together) he's not really into the whole PDA thing. (Public Display of Affection), which is fine with me, but I don't know how to kiss him without making it awkward for him since a few of our friends will be there. Any ideas?
