The 27-year-old YouTube personality has talked about sex and dating since 2008, and has over 1.5 million subscribers.

In addition to the YouTube channels Sexplanations and Hannah Witton, there's Laci Green. Online videos have attempted to educate about sex before. If not, she suggests you stop and take a break. If you do everything 'right,' the voice lets out a satisfying sigh. The lessons end when the screen fades to white. As you touch, a voice-over softly guides you where to touch and how fast. These images are created from thousands of composited, high-definition photographs stitched together from some of OMGYes' interviewees, who range in race, age and body type. Viewers can, for example, use their fingers to rub and tap digital renderings of female genitalia on a touchscreen.

Berkeley graduates Lydia Daniller and Rob Perkins, OMGYes is a startup dedicated to 'the science of women's pleasure.' Its videos feature one-on-one interviews with women like Rosalind who share their sexual history and favorite techniques. The company is in the process of producing its second season. Sites like OMGYes, Orenstein says, 'have the opportunity to do an end-run around traditional sources of education - and miseducation.'

'The internet has offered, along with a lot of really disturbing images and ideas, a lot of potential for positive education,' says Peggy Orenstein, author of 'Girls & Sex' and 'Cinderella Ate my Daughter,' which examines how modern culture sexualizes young girls. Serving a space somewhere between the staid, impassive lectures many sat through as students and a pornography industry that values entertainment above all else, these companies use interactive and user-generated digital media to explore the more emotional, intimate and vulnerable sides of sex. OMGYes is one of a number of companies ushering sex education for the 18 and older crowd into a new era. They're filming for OMGYes, a site that hosts a series of online videos about how to sexually satisfy a woman. 'That's literally the first time I have ever said that out loud.'Ī few crew members chuckle. 'I can't believe I told you guys about the shower masturbation,' says Rosalind (not her real name). Sitting on a couch as SLR cameras record her, she gets ready to tell nine people, none of whom she's met in real life before, about the first time she masturbated. The 24-year-old research assistant wears a thin green utility jacket and has large brown eyes and dark wavy hair with pin-up-girl bangs. In the sunny living room of a Mediterranean-style house in Oakland, California, Rosalind sips coffee through a straw. It contains sexually explicit descriptions and may not be suited for younger readers.
