Jewish American actress Rachel Bilson has revealed she lost an ad deal after having a frank conversation about sex on her podcast.

Speaking with sex therapist Emily Morse in a new episode of Bilson's podcast, Broad Ideas, the actress said comments she made last month were "taken out of context."

While many headlines stated that she'd never had an orgasm until 38 years old, Bilson said: "That's not what I said and that's not true." She pointed out it was not until she was in her 30s that she achieved an orgasm through penetrative sex.

"I hadn't even tried a toy [until then], and it was given to me as a gift,” she said.

The 41-year-old voiced frustration that sex is "such a taboo topic" for women to discuss publicly.

"So many women feel like they can't talk about if they're not having an orgasm or what's helping them have an orgasm," The O.C actress said, adding that it was "so important" to diminish the taboo surrounding female sexuality.

The mother-of-one’s frank comments on sex come just a few weeks after the actress revealed that she lost out on an unspecified endorsement deal due to her sexual podcast conversations.

"It's been an interesting week, guys. This is the first time it's ever happened to me in my professional life that I lost a job this week because of things that were said."

"A job got taken away from me because I was speaking candidly and openly about sex in a humorous way on our friend's podcast," she explained. "I basically got a job, that I already had, pulled from me because I was speaking openly about sex."

The actress had been speaking about her favourite sex positions when she, in a “joking manner”, said she liked being “manhandled”. "First of all, I said it in a joking manner in the interview, like, 'Yeah, I wanna get f**king manhandle... give control or take control in the bedroom, whatever."

While she admitted her delivery could have been different, Bilson said the sentiment remains the same.

"I haven't said anything inappropriate," she maintained. "Choice of language, if I could go back, now knowing I lost a job, maybe I would say it differently. But I still wouldn't not say it."

Bilsen, who has an Italian Catholic Mother and a Jewish father, has previously shared that she grew up in a "Chrismukkah household".

Bilson told Parade in 2011: “In my family, we’re very spoiled in the food department. My dad’s side of the family is Jewish, and my great-grandmother made amazing matzo ball soup, noodle kugel, and mandelbrot. My m[u]mm’s side of the family is Italian, and when we have dinner for a large crowd, it’s usually ravioli or ­eggplant Parmesan.”

Her British great-grandfather, George Bilson, who was born into an Ashkenazi Jewish immigrant family in Leeds, England, and worked for an American film production company after immigrating to the United States.
