Miley Cyrus Opens Up About Sex: Stop the Guilt!

Miley Cyrus says we need to talk about sex more.

Especially with young people who think it's OK to have unprotected sex.

"I think that most of it is just having the conversation and taking away the kind of embarrassment or guilt that people feel attached to sex," Cyrus tells me.

The "Wrecking Ball" singer is sounding off on sex because she's the new face of MAC Cosmetics' iconic Viva Glam campaign. Proceeds from a hot pink lipstick and lip gloss created by Cyrus benefit the MAC AIDS Fund.

"I think the way sex has been made to be seen as bad or guilty, I think it's just opening up that conversation that's saying if you're doing it, protect yourself. And I think young people need to be talking," Cyrus said.

Earlier in the day, Cyrus visited the Los Angeles LGBT Center's Youth Center to meet homeless youth and to learn more about HIV prevention.

She impressed that when "you walk in, there is a bowl of condoms right there. You didn't have to ask."

Cyrus praised the Viva Glam campaign because it wasn't about making a profit.

"You don't see me kind of doing this stuff very often," Cyrus said. "I'm not the person to go out and say, 'Buy my lipstick,' or 'Buy my this, or, 'Buy my that.' This was something I obviously didn't mind saying...and kind of shamelessly plugging because it's going towards such an amazing thing. Every penny of it! It's not halfway going to help and halfway paying someone's salary. It's a hundred percent!"

Go, Miley!
