In regards to her partner, Ms Chao, 34, added that "it would mean the world to me if you could just not be so terrified of her, and treat her like a normal, dignified human being."
She writes: "I do love my partner Sean, who does a good job of looking after me, ensuring I am fed, bathed and warm enough every day, and generally cheering me up to be a happy, jolly girl. She is a large part of my life, and I am a better person because of her.
"I'm sorry to mislead you to think I was only in a lesbian relationship because there was a shortage of good, suitable men in Hong Kong.
"There are plenty of good men, they are just not for me."
In a separate interview with The Times, she said: "Since Dad thinks it's so easy for me to switch from gay to straight, I should just leave it for him to demonstrate. I think I'll marry a man when he marries a man," she said.
The South China Morning Post, one of the papers that published the letter, reported last week that Ms Chao has received "strange" phone calls from would-be suitors since her father made his comments, and that most open by saying, "I want to be a billionaire!"
In an interview with the newspaper last year, Ms Chao said it was difficult dealing with the sudden publicity after Mr Chao "threw her out of the closet", because "Hong Kong is horrible at accepting and welcoming diversity".
Ms Chao is an executive director of luxury property development company Cheuk Nang, which has projects in Hong Kong, China, Macau and Malaysia. Ms Chao is now considered as a LGBT activist and has become closely involved in Big Love Alliance, a gay rights group that lobbies the government to pass anti-discrimination legislation.
