Sleeping shirtless

I have always been shy and hesitant about going shirtless from the time I was a kid.

I couldn't no matter how much I wanted to.
I used to sleep and want to remove my shirt but for some reason it never happened. I thought maybe I'm too fat but in the pic there's a similar sized guy to me comfortable sleeping without a shirt


The bottom pic is me
I jus took a random pic to fix d out if there's anything wrong with me because there's much bigger guys than me but way more confident also

I'm also still trying to overcome sleeping shirtless properly
