Documentary: Virgins Wanted.

As far as I can tell, this is legit (check the crazy terms and agreements here - of course, they got the hymen aspect totally wrong). Trailer:

Virgins Wanted follows one man (Alex) and one woman (Catarina) as they defy social norms, putting their virginity up for auction to the highest bidder. The series examines their motivations behind remaining virgins, as well as their day to day lives and their hopes and dreams for the future.

The homepage is here.

Currently, the highest bid for Catarina is $450,000 - the highest bid for Alexander is $2,500. This massive difference is not surprising. If you rule out attractiveness, there are likely two other factors at play: (1) men's interest in, and willingness to, pay for sex; and (2) that women's virginity is considered a much more valuable asset than men's.
