Giselle, 19, put her virginity for sale on the notorious Cinderella Escorts website, which hosts listings from across the world.
The American model says she put her first experience of sex up for sale so she can pay her tuition fees and go travelling.
“Every woman has to decide on her own if it is worth to give her virginity for free to a boyfriend who maybe later on will break up with her, rather than selling it,” she said.
“But I made my decision and now I can study wherever I want, buy a new house and travel around the world. It gives me a lot of opportunities.”
