After changing his name from Greg to Golden and swapping building sites for parties, he’s carved a niche for himself as one of the world’s busiest gigolos.

Golden – whose female clients include a Hollywood actress, a swimwear model and the daughter of one of the richest men in London – says: “I’m probably one of the luckiest men alive.

"It’s not a career, it’s a lifestyle – and I absolutely love it.

“People ask me if I have any regrets, but as I’m sitting in an amazing penthouse in New York overlooking Central Park and about to have wild sex with a beautiful, blonde financial consultant worth millions of dollars, all I can think is ‘wow’.

"This is a fantastic way to live.”

Now Golden, who’s 30, is telling all (except the real names of his clients) in a raunchy and revealing book about his life entitled Gigolo.

But he hasn’t always been so fortunate with the opposite sex.

He explains: “When I was a teenager I was rubbish with girls.

"My first sexual encounter happened when I was 17 and it was certainly nothing to write home about.”

Golden says his luck changed when a musician he met started taking him to wild parties attended by rich women.

He explains: “I was introduced to a life of fast cars and fast women, who I realised were willing to fund my champagne lifestyle in exchange for no-strings sex.

“From that moment I never looked back, and I gave up my building job when I was 20 to be a full-time gigolo.”

Golden, who always practises safe sex, has slept with hundreds of “young, gorgeous and successful” women in the 10 years since he became a gigolo.

The women he meets pay for him to travel around the world, often first class, to act as arm candy and service their needs.

But despite being surrounded by luxury, he has very little money of his own.

“I am not a male prostitute,” he protests.

“I’m not given cash.

"Women pay for meals, drinks or hotels, and shower me with gifts like cars and designer clothes.

"I love it and I don’t see anything wrong in it.”

Golden, who lives in a flat in upmarket West Hampstead, London, says that even though he works as a gigolo, he still has conventional girlfriends too.

“I dated a waitress.

"I came clean about what I did and she was fine, but it ended after a few months.

"It wasn’t anything to do with my lifestyle, it just didn’t work out,” he says.

“My parents both know what I do and they are very proud of me.

"My dad worked as a builder all his life and we were brought up with good values.

"He always tells me he’s happy that I’ve had so many experiences.

“I love and respect women.

"I have a friend who fell in love with one of his clients and married her.

"Who knows? One day that could happen to me.”

DIARY OF A GIGOLO

SUNDAY

Wake up alone around 1pm in my London flat. Go to a café for breakfast then for a walk on Hampstead Heath. Sunday is my day to play my piano and write music. In the evening I call up Rochester, a fellow gigolo, who’s very rock ’n’ roll and always knows the best parties. Tonight is my monthly meeting at the Café Royale in London – strictly boys only – which is when six of us gigolos meet up to discuss trade. Get a midnight call from Trustfundia, my gorgeous client with a super-rich daddy and a super-swanky home in central London. I jump in a cab (she pays at the other end) and the champagne is already on ice. After we’ve had amazing sex, her driver takes me home.

MONDAY

Wake up around midday and get a text from my Miami-based gigolo friend, ZZ, who wants me to go out there because lots of fashion swimwear parties are happening. His patroness is a very rich former porn star who’ll pay for my flights. I pack my red Armani slim-fit swimming trunks (flattering but not too tight, which is naff) and head to Heathrow for my first-class flight.

TUESDAY

Get picked up by ZZ in his scarlet BMW. He tells me the party’s already started. We stop off at a costume shop where we pick out outrageous outfits (girls always like a man who’s confident enough to make a fool of himself and up for a laugh). I’m in a tight white Versace-style shell suit covered in gold anchors. We pull up outside the porn star’s art deco home in South Beach, where her work colleagues are pole dancing and drinking in the sun. Head to the Rokbar club with ZZ for a few hours, before being called back to the party which is beyond debauched. The best gigolos don’t do drugs because they age you and affect your performance. Have fun with ZZ’s friend before being ‘used’ by the other girls to show off different sexual techniques. It’s a hard life.

WEDNESDAY

Wake up at 1pm and wander over to the luxury Delano Hotel for breakfast. Sit by the pool and get a text from my wealthiest American client, Miss Alpha, a hedge-fund investor who wants to take me to a party. Luckily, I’m already in America. Her PA sorts out first-class flights to New York. When I arrive I’m picked up in a black limo and taken to her skyscraper flat. She is blonde, gorgeous, and knows exactly what she wants – sex, right now. She drags me into the apartment and pulls off my clothes. We have sex on her giant bed in front of a TV screen that doubles as a mirror.

THURSDAY

Shopping day. My reward for services rendered. Miss Alpha takes me to Saks department store to buy me a Hugo Boss suit, shirt, ties – even underpants – the total bill is around £13,000. She insists on dressing me in a cream jacket and matching brogues for an art exhibition. Go to the gallery and see her multimillionaire friends. I feel totally confident. On the way home from the gallery, Miss Alpha insists on sex in the limo, watched by the driver.

FRIDAY

Fly home to London. I fall asleep for a few hours then go to my local arts café. Here I can relax, play the piano and flirt with the waitresses. Call up Rochester to check out the parties. Decide on a boys’ night out at the London club Boujis. We’re a big hit with the Pashmina Princesses (rich girls hoping to bag a young royal). We’re bought champagne then move on to Paper where we meet four beautiful Essex girls. Go back to their place to have fun, and they give me my cab fare home.

SATURDAY

Gigolos need to look after themselves because looks are important. Lots of sleep is required, and Saturday is the worst night of the week to go out. This is my day to do absolutely nothing. I think I deserve it.

Gigolo by Golden (Hodder & Stoughton, £6.99) is out on June 12.

Does Greg’s life sound appealing to you? Do you do something similar to Greg – if so, do your friends and family know? Would you be proud of making your living as a gigolo or an escort? Greg says it’s not prostitution because he doesn’t receive cash, but is it really that different? At what point does this lifestyle become too much?
