My physical appearance. I don't think I'm particularly bad looking. I'm slimmish, dark blond, blue eyes etc, but I have man boobs. It's destroyed any self confidence I would have had. I always have to wear pretty baggy shirts to try and hide it. Topless on a beach or in the sun is a no no. My daughter has been swimming once in two years cos I'm terrified of taking my shirt off in public.

So yeah... that.
