Los Angeles, Sep 16 (IANS): Actress Jessica Biel is set to launch sex education series online to teach women more about their bodies.

Inspired by questions she had while trying to conceive, the "Total Recall" star has teamed up with activist Saundra Pelletier to educate women on how their bodies work, reports people.com.

Now the mother of five-month-old Silas Randal, Biel recalls what a confusing time it was for her when she got off birth control, and was left with questions like "I've been on the pill for so long; how hard will it be to get pregnant?"

"Suddenly I realized I really didn't know what's going on inside my own body," Biel, 33, told Glamour magazine. "It was shocking."

Pelletier, founder of the non-profit WomanCare Global, had experience helping women and girls in Africa who didn't have access to menstrual protection, but only just focused her efforts on the need for information in the US.

"More than half of our nations pregnancies are unplanned, and just 22 states require public schools to teach sex education," said Pelletier. "Jessica and I realized we can help change this."

Biel added that you have to have the "courage to stand up for what you believe in".

With that in mind, the duo are launching a series of videos that will discuss issues that affect women, including everything from puberty to contraception. Their hope for the videos, which will be shared at womancareglobal.org, is that by helping girls better understand their bodies; they won't feel embarrassed or afraid of what's happening.
