Youd be totally justified in being wary of Gwyneth Paltrows Netflix series The Goop Lab and its promised alternative outlook on wellness, based on Goops questionable past and the series promotional imagery : a wide-smiling Paltrow standing inside what appears to be a vagina.

Or wait isnt it a vulva? (Spoiler alert: It is.)

But if you didnt already know that, the third episode of the controversial series offers viewers a basic anatomy lesson that helps answer that very question.

The episode, The Pleasure is Ours, seems to be the most well-received of the series, thanks to 90-year-old sex educator Betty Dodson , her no-bullshit attitude, and her protege Carlin Ross. In the episode, Dodson and Ross discuss their work destigmatizing pleasure while helping women find self-acceptance (and orgasms).

The Board of Gynecologists came out and said, We know [Paltrow] screwed up with the vagina eggs , but this episode has real information, and we stand behind it, Ross told HuffPost over the phone last week. I was like Whoa, she said, laughing.

Ross, an attorney, joined Dodson on her decadeslong mission in 2009 after interviewing Dodson, who has a Ph.D. in sexology and is widely regarded as a pioneer in womens liberation, for a podcast. They shook on the partnership that day, and Ross now calls herself keeper of all things Betty Dodson . She runs their website, is president of the Betty Dodson Foundation and leads their workshops and certification program.

Both Betty and I saw in each other that weve always been criticized for being too aggressive, too male, Ross said. Whenever you know what you want, do what you want, like to have a fifth drink, like to have a good fuck, its like, Oh, youre a man. Im not a man. Im a full woman.

That confident attitude contributed in part to Ross agreeing to show her vulva, masturbating and orgasming on screen during their Goop episode, which features Dodsons Rock n Roll technique .

Ross told HuffPost she was the one who suggested appearing so openly in the episode, but she was in denial about whether it would actually happen.
