Rosie Reid, 18, from London, decided to auction her virginity on the auction site eBay in order to avoid graduating with huge debts.
The Bristol University social policy student says she would rather sleep with a stranger than face years of comparative poverty.
Ms Reid put herself on offer earlier in January and received more than 400 offers within three days, including one of £10,000.
On the eve of a Commons vote on higher education funding, more than 250 students in the city demonstrated in an attempt to persuade MPs to vote against top up fees.
Can Okar, President of the University's Union, said: "We hope to keep the vote at the forefront of the minds of MPs.
"We want them to vote with their conscience. Education is too important to get tied up with politics."
Speaking about Ms Reid, he said: "We would never condone anyone putting themselves into a dangerous position.
"It is a great stunt but this is a serious issue and this student is setting a bad example to others."
Commons vote
Ms Reid said: "It started as a joke, and ended up as 'why not?'
"I am devoting too much time to paid employment and not enough to studying. I am not achieving as much as I could."
The student from Dulwich currently works lengthy hours in order to pay for tuition fess and living accommodation in Bristol.
"I'll leave university £15,000 in debt. That's why I am taking this drastic action."
On Tuesday, Parliament is due to vote on top up fees with several rebel Labour MPS threatening to vote against the government.
Auction website eBay has withdrawn the offer, although Ms Reid says she will continue the auction on her own website.
