Im i the only one who thinks french kissing is tedious and boring activity?

My girlfriend really like to snog, and im always thinking i would rather be doing something else. Sometimes i think of something funny my mate said or just that i really have to pee. Im also not very good at it, so i wonder why she persists. She especially beckons this activity when her friends are around, and i think 'aren't they going to get a bit uncomfortable'.
