I have liked shirtlessness since I was little, for some reason... I always tried to sleep just in shorts, if I felt cold I used blankets, in the summer I liked being shirtless during the day as well, I also went to the store shirtless, or to play with friends. When I started to go running when I was around 15 or 16 I usually went without a shirt as well, it just felt good to feel the air and all and besides, it was more comfortable. Overrall I like being shirtless whenever I can, even take taxis shirtless sometimes or just when I'm walking somewhere. It is just great.
