Sometimes I wonder why some animes show the body measurements of male characters. I don't think girls care about that information as boys do.
I think it has do with the culture itself. In Japan, they do physical exams of both girls and boys. They take measurements of the girls and only weight and height for the guys. Somehow, it became a big thing along the way. I seen shows where some gals who love the assets of guys or the size of their biceps. Gou Matsuoka is one crazy character I seen. She loves biceps, triceps, and more.
