Talk about virgin air. A 20-year-old Brazilian woman is auctioning off her virginity for a one-time tryst on an airplane, reports say.

To make the skies even friendlier, Catarina Migliorini says she'll donate some of the money to provide housing for poor families in her native Santa Catarina in southern Brazil.

The Internet bidding reached $160,000 Friday afternoon. The auction ends Oct. 15.
