TLDR: I have a too forward chest skeleton because I fucked it up as a kid. Normally, I look like a loser. If I stand straight, some guys look at me like they challenge me. How do I stand straight and keep away some guys from trying to stare me down? I want to mind my own business. I want people to be okay with me instead of resorted because I live in society. Should I smile at guys? Should I nod? What do I do? My relaxed face looks sad and serious. Stand straight and permantent smile?

Length of my chest from that angle is considerably wider than average male. From side view, chest measurement is around 3 inches longer than my head measurement, unlike this. When I was a little kid, I was insecure and hunched myself to hide my belly. I grew up sitting in front of computers. Often tshirts and tight jackets look weird on me because one side stands lower than the other on the bottom. I also have trouble breating if I stand straight while running because I fucked up my skeleton. Or maybe its genetics. Doesn't matter.

When I stand straight, I feel like I look like I am buffing myself up like a chicken. My head is so flexible on top of my chest that I can look like a complete loser or I can look like I have a beef with you. You probably don't know what I am talking about because you are normal. The more my head goes back, the more women give me eyes and the more man look at me like they are weighting me or look at me like they are trying to challenge me.
