Another leftie here ! I have tried to play a couple of my friend guitars as right handed but the hand coordination wasn't there. I got my guitar after playing Guitar Hero games. Was playing it in leftie mode, so got a left handed guitar, haven't dropped since. It feels easier to be honest. Also with normal guitars, i'm focusing on my right hand so much that I forget to move my left while playing the strings. As a sidenote, my air guitar sessions were with left handed guitars too. So try the air guitaring on a random occasion and check your movements.
