'I had sex with a man once': Cher's son Chaz Bono on how he experimented with his sexuality

Pop singer Cher's daughter-turned-son Chaz Bono has revealed how he had sex with a man once - just to know what it was like.

The 42-year-old, who is three years into a female-to-male gender reassignment process, told U.S. TV host David Letterman that he has never dated a man.

Bono described how he felt very uncomfortable with his body during puberty, a feeling which intensified with age...

He went on to reveal that he had sex with a man once just so he could 'know for sure' about his sexuality.

Talking about his 64-year-old mother was coping with his transformation, Chaz, who was formerly known as Chastity, admitted it had 'been a process' for Cher, but added that she is progressively getting 'more and more comfortable with it'.

Letterman then asked him: 'Now is there anything different about her I should know about?'

Replying with a laugh, Chaz, who has been dating  girlfriend Jennifer Elia  since 2005, retorted: 'No! It's not catching!'

Chaz is currently on a promotional tour plugging his new memoir - Transition: The Story Of How I Became A Man - as well as a TV documentary.

Becoming Chaz premiered on Oprah Winfrey's OWN network last Tuesday.

Cher spoke to Letterman back in November, she she threw her support behind her son's decision to have a sex change.

She said at the time: 'I was saying to someone the other day, I really like being a woman, I feel so comfortable in my body, and if I woke up and I was in a man's body, I'd think, "Oh my God, I've got to get out of here."

'And that's the way Chaz felt, it was never comfortable - he's very comfortable now.'

Chaz also told E! news this week that he would love to talk to Brad Pitt and Angelina Jolie about their daughter Shiloh, who has received attention for her tomboy style.

Bono, who does volunteer work for a support group which helps children with gender identity issues and their families, said: 'I would love to talk to [Brad and Angelina] at some point... to at least let them know we have this resource for them if they ever need it.'
