Aubrey O'Day Thought Sex Was 'Disgusting' In High School, On 'When I Was 17'

'When I was 17, contrary to popular opinion, I was a virgin,' former Danity Kane singer says.

These days, Aubrey O'Day is known as a sexy pop singer who, among other things, has appeared in a Vegas stage show nearly nude. But back in high school, the Playboy model thought sex was kind of gross. On this week's episode of "When I Was 17," O'Day admits that having sex was not her number-one goal in life.

"When I was 17, contrary to popular opinion, I was a virgin," the onetime Danity Kane singer confesses on the show, which also features former baseball captain Donald Trump and Nick Cannon. "I was very scared of boys. I was very insecure about my body and I thought anything sexual was disgusting."

While it may be hard for fans to believe that O'Day, who regularly poses wearing very little in photo shoots and very openly discusses her bisexual love life, was a prude in high school, her friend Melissa confirms that she was in fact kind of a sexual wallflower, explaining, "I think the idea of sex just kind of freaked her out."

O'Day was apparently so scared of boys that her friends weren't even sure if she liked them at all. And forget about having a discussion with O'Day about sex — that was even weirder for her. "I'd get, like, creeped out if I even heard my friends talking about it, and all my friends were having sex," she explained. "And I was just the one that didn't ever have a boyfriend. People probably thought I was a lesbian."

"When I Was 17" — this week featuring Donald Trump, Nick Cannon and Aubrey O'Day — airs Saturday at 11 a.m. on MTV.
