When the North Korean defector Jang Yeong-jin arrived in South Korea in 1997, officials debriefed him for five months but still hesitated to release him. They had one crucial question unanswered: Why did Mr. Jang decide to risk crossing the heavily armed border between the two Koreas?
“I was too embarrassed to confess that I came here because I felt no sexual attraction to my wife,” Mr. Jang said. “I couldn’t explain what it was that bothered me so much, made my life so miserable in North Korea, because I didn’t know until after I arrived here that I was a gay, or even what homosexuality was.”
