Sleeping Shirtless

[image/video - please log in to see this content]

Someone recently advised I should try and sleep shirtless to get more confidence.

When I was younger, I did it couple of times but some weird anxiety made me to put a shirt on in the middle of the night

I'm waiting for our warmer weather and I'd like to try

Did anyone else have this issue or was it jus something normal to everyone, like jus remove your shirt?
