This is how I started going shirtless outside when I was younger. I liked doing this when going on a bike ride. I would ride for awhile then find a quiet spot where there weren’t a lot of people and take my shirt off, then keep riding. It was incredibly exciting. As I kept doing this I got more confident and went shirtless more and more and doing different things like driving, going on a walk, etc. I think men should be more comfortable doing being without a shirt outside. It’s really a lifestyle to me now.
