Arguably one of the biggest musicians in the world right now, Billie Eilish has caused waves online with an incredibly candid admission.

The 22-year-old star sat down with Rolling Stone to talk about everything from her latest album and how she has grown as a person to what she does in her spare time.

And it’s fair to say, Eilish left no stone unturned.

The musician revealed that she was her best self in 2019, just after she released her first studio album, When We All Fall Asleep, Where Do We Go?, and with her new album, Hit Me Hard and Soft, coming out this year, she has recaptured the freedom and youth of five years ago.

But despite all the hype around her new music, the attention surrounding the interview is primarily around the comments she made about her favourite subject matter.

The Los Angeles-born pop star was asked what she likes to do to decompress to which she simply said: “Sex.”

Eilish continued: “I basically talk about sex any time I possibly can. That’s literally my favourite topic. My experience as a woman has been that it’s seen in such a weird way.”

She noted how people are ‘so uncomfortable’ talking about the topic, and questioned why many feel weird about women feeling comfortable in their sexuality – something she said should change.

The What Was I Made For? singer said that sex can really ‘save you sometimes’ and that she ‘can’t recommend it more’.

She then made an incredibly x-rated admission about masturbation, saying that self-pleasure is a huge part of her life and that ‘people should be jerking it’.

Eilish then admitted that she enjoys masturbating in front of a mirror.

She explained: “Partly because it’s hot, but it also makes me have such a raw, deep connection to myself and my body, and have a love for my body that I have not really ever had.

“I got to say, looking at yourself in the mirror and thinking ‘I look really good right now’ is so helpful.”

Eilish said that you can change the lighting, wear something nice, or sit in a flattering position to get the most out of the experience.

“I have learned that looking at myself and watching myself feel pleasure has been an extreme help in loving myself and accepting myself, and feeling empowered and comfortable,” she claimed.

The 22-year-old also said that she ‘should have a Ph.D. in masturbation’.

Eilish also voiced her frustrations at the media for focusing so much on her sexuality, opening up on the moment that she realised she liked girls.

She added: “I’ve been in love with girls for my whole life, but I just didn’t understand until, last year, I realised I wanted my face in a vagina.

“I was never planning on talking about my sexuality ever, in a million years. It’s really frustrating to me that it came up.”

The star clarified that she liked both boys and girls in an Instagram post last year, but also concluded the post by saying: “Leave me alone about it please literally who cares.”

On X, people reacted to her admissions about masturbation and sex, with one user posting: “Why did we need this information.”

Another put: “Some things are better left unsaid.”

In contrast, a third showed support: “She’s so real for this share actually.”
