Chaz Bono, son of international star Cher, has spoken candidly for the first time about his sex change, which he started in March this year.

Speaking on the US television show ‘Entertainment Tonight,’ the forty year old, who’s name was formerly Chastity, said:

“I always felt like the male from the time I was a child. There wasn’t much feminine about me,

“I believe that gender is something between your ears, not between your legs. That is something I discovered in the early ’90s.”

“It lowered my voice,” he added, “fat redistributes, muscle growth, hair growth, sex drive increases.”

“It was just a long process of being comfortable enough to do something about it.”

Bono came out to both parents as lesbian at age eighteen. In autobiography ‘Family Outing’, Bono wrote:

“As a child, I always felt there was something different about me. I’d look at other girls my age and feel perplexed by their obvious interest in the latest fashion, which boy in class was the cutest, and who looked the most like cover girl Christie Brinkley.

“When I was 13, I finally found a name for exactly how I was different. I realized I was gay.”

Last month, it was revealed that Bono signed a six-figure publishing deal for a memoir tentatively titled ‘Coming Clean’.

It is scheduled to hit shelves in 2011.

The 40-year-old is Cher’s only child with late husband Sonny Bono. He is a gay rights activist but also works as a musician, writer and actor.
