This has happened time and again. A few years ago, a girl put up a trend by getting money by auctioning her virginity; she needed money to fund her higher studies, and was willing to sleep with anyone who paid the most amount of money. This was innovative, and she got enough money to fund her studies. At that time, there was condemnation for this sort of moral grey issue, but now seems to be something that other girls have also adopted, since we keep on hearing this time and again.
Now, there is another case of this happening, where a girl earned $32,000 dollars by auctioning her virginity online, and in the country of New Zealand, this is not illegal. If the girl does indeed go through with this arrangement, she would have got money to pay for her college fees (link to article):
A New Zealand teenager who says she auctioned her virginity online for $32,000 to raise tuition money did not break any laws but it might be risky for her to follow through on the deal, police warned Wednesday. She said in a post that more than 30,000 people had viewed her ad and more than 1,200 had made bids before she accepted an offer of more than New Zealand dollars 45,000 ($32,000).
Prostitution is legal in New Zealand under laws considered more liberal than many countries. Prostitution among consenting adults is allowed in brothels and on the streets, and offering sexual services in print ads and online is also legal. National police spokesman Jon Neilson said no law appeared to have been breached.
