Holly Johansson has revealed how for the first 18 years of her life, she grew up as a boy called Kasper and began modelling.
But, in 2007 Holly, made a decision to start living as a woman and since then, Holly, now 26, claims booking have gone through the roof.
She even appeared on Playboy TV Chat under a false name for six-months and seduced nearly 1,000 men on televised sex chat phone lines - some of whom didn't know she was born male.
I only tell people that I'm a transsexual when I want to, or if a situation could develop into something more physical.
"There have been a few instances where I've assumed guys know I'm pre-op transsexual.
"I was getting close to one guy I met in a pool but then when we were back in my hotel room he realised that I still had my penis and screamed.
"He was naked and I had just my underwear on, suddenly he started shouting because he couldn't believe I was pre-op.
"Another time a guy ran off yelling and even left behind one of his shoes."
She also appeared on video sex chat lines on adult TV stations including Playboy TV Chat, the Red Light TV chain and Single TV.
She said:
"I don't always disclose that I'm a pre-op transsexual in modelling jobs because in the past I've had people turn me away once I've told them my secret.
"When I worked on the adult channels I tricked a lot of the guys and they didn't know I was a transsexual when I was on the talking to them on the phones.
"The guys who called up would talk dirty things to me as if I was a woman, but I would never correct them.I didn't want the fact that I'm transgender to ruin my modelling career so at times I'd just lie to them and they were none-the-wiser."
