I'm one of those guys with permanent Fat Kid Syndrome. Even though I've grown and thinned out, there will always be a part of me that sees myself as the chubby 8th grader with man-boobs. Because of that, I've always had a slumpy posture, I've made the bad habit of pulling the bottom of my shirt to disguise unwanted folds, etc.

However, I noticed that there were only two kinds of people I felt totally comfortable "puffing my chest out" around: Close guy friends and girls who have already seen me naked. Being around someone who has seen your biggest insecurity and accepted it will instantly put you in your comfort zone. So how can this help us with strangers? Pretend they have already seen you naked.

This might seem counterintuitive, but think about the way you walk around when you're alone in your underwear. Better yet, think of that post-sex "I'm gonna go use the bathroom" strut you do with zero shame. What gives you such confidence? The fact that your fears have just been put to rest. As it turns out, you're fine the way you are.

And for you virgins, don't fret. That day is soon to come. Just put on your best nude strut and get out there.
