The idea that virginity has a high value harkens back to the days of early humans — if a man has sex with a virgin woman, he knows for sure that her children will be his, anthropologists reason. In early civilizations, women were also considered the property of men, said Laura Carpenter, assistant professor of sociology at Vanderbilt University in Tennessee.

Through the 1950s in America, women were expected to remain virgins until marriage, Carpenter said. But with the availability of the pill and the IUD in the 1960s, combined with youth counterculture and gay rights movements, it became more common for women to engage in premarital sex, she said.

Attitudes shifted toward the conservative side in the 1980s with the worldwide HIV/AIDS pandemic, which made the stakes much higher for choosing a sex partner, especially for men. Abstinence-based education programs also took off around that time, with government support, she said.

Today, about 95 percent of Americans have sex before they’re 25, Carpenter said. But worldwide, virgin prostitutes can claim larger fees, certain cultures still attach larger dowries to virgin brides, and some women undergo reconstructive surgery to restore their hymens.

In looking at Dylan’s auction, “To some extent it’s not new. The new part is the Internet,” Carpenter said.

And Dylan’s take?

Some men may seek virgins because they want them as trophies, or desire purity. But as to why men would bid so much money on virginity, she said she has no answer.

“I honestly don’t know what they see in it,” she said.

If you think Dylan’s auction amounts to prostitution, she completely agrees. She also said she’s not breaking any laws — after all, prostitution in Nevada is legal.

“I feel people should be pro-choice with their body, and I’m not hurting anyone,” she said. “It really comes down to a moral and religious argument, and this doesn’t go against my religion or my morals. There’s no right or wrong to this.”
