Laura Michaels, 23, set up a group called “I Need Sex” on the site.
She invited men to contact her and those whose picture she liked, she met up with.
Within 10 minutes the group had 35 members and soon attracted 100 men, 50 of whom she slept with.
She told The Sun: “I know that it was risky behaviour but that was part if the thrill.”
One of her Facebook conquests was called Simon from Swindon.
She said they met for drinks in her home town of Bristol and then went back to his hotel for sex.
She admitted some people might “look down on me” for her behaviour and said some might even say that she may as well have been a prostitute because then she would at least have been paid for sleeping with so many different men, but she said: “I don’t see it like that at all.
“I was satisfying my own desires by setting up the group.”
She said Facebook had since removed her page.
Casual sex encounters on Facebook have been linked to a rise in Syphilis in the North East.
