RIO DE JANEIRO (AFP) - A 21-year-old Brazilian woman who auctioned off her virginity online for $780,000 (S$970,000) last year now says she wants to sell it again as the deal was never consummated.

In October last year, Ms Catarina Migliorini took part in an online auction as part of the "Virgins Wanted" documentary organised by Australian film-maker Justin Sisely.

A Japanese identified only as Natsu beat out competition from 14 other men, mainly from Brazil, but also from India, Australia and the United States.

But in a video, Ms Migliorini now insists: "I am still a virgin in every sense of the word and no one can prove me wrong."

The young woman, who posed nude next to a pink teddy bear in Playboy magazine, opened her own website VirginsWanted2.com to hold a second sale of her virginity to the highest bidder.

"I decided to open my own webpage to auction off my virginity and this time it will be for real. So those interested, men or women, can make their bids," she said.

She told the Brazilian showbiz website PurePeople.com.br that she hopes to bring in at least US$680,000.

So what really happened with Natsu last year?

"I met Natsu in a Sydney restaurant. He was not a 53-year-old man as Justin (Sisely) claimed. He was a 21-year-old Japanese. I was surprised and no deal was struck between him and I," said Ms Migliorini, who added that she will give details of the failed transaction in an upcoming book.

It was not clear whether Ms Migliorini ever received any money from Natsu.

Meanwhile Ms Migliorini's mother, Mary, said she was "flabbergasted" by her daughter's decision, according to PurePeople.com.br.

"I don't approve but I won't stop loving her. I love my daughter unconditionally... But I don't get this," she added.

According to Britain's Daily Mail, Ms Migliorini's decision to sell her virginity to the highest bidder last year sparked outrage across the globe, with some claiming she was little more than a prostitute.

But she then defended the move.

"I saw this as a business. I have the opportunity to travel, to be part of a movie and get a bonus with it," she was quoted by the Mail as saying.
