"I was very angry, very rebellious," Martin explained to GQ Australia. "I used to look at gay men and think, I'm not like that, I don't want to be like that, that's not me. I was ashamed."
Martin continued, "When you're told you're wrong by everyone, from society, from your faith — my self-esteem was crushed. I took my anger out on those around me."
The 41-year-old singer came to the realization that this was a defense mechanism -- a way to fight off who he really was.
