Senjuro gay?!

He (Senjuro) was always told that when he grew up, he would marry a girl and start a family with her. But Senjuro had never been attracted to this idea, even as a teenager. Usually at that age, girls start to be attracted to boys. But Senjuro... None of the girls in the village attracted him romantically. And this worried him, thinking that perhaps everything would appear a little later. But at that time, he began to notice himself often looking... At boys. Those who came to train with his older brother, Kyojuro. At first, he thought he was envious of their strength, because he himself was frail and weak. But then he began to stare at them more and more. And this worried him. He secretly bought a book that explains all sexual orientations, and after a little research, he realized that he was attracted to boys and only boys! This was terrible, because the family expected heirs from him. He considered himself wrong and a mistake because of this, and tried to push these thoughts away, but he could not. He didn't tell anyone he was gay (a guy attracted to guys), thinking everyone would turn away from him if he did. And what were the chances he'd meet a guy like that here, in a place where such things were frowned upon?
