Planet Sex With Cara Delevingne Season 2 is yet to be announced by BBC iPlayer

Cara consults a cosmetic surgeon and investigates where our ideas about beauty come from. She explores colourism in South Africa, plastic surgery in Colombia and talks body positivity everywhere.

Love has always fascinated Cara. It's time to think beyond monogamy. Cara takes a DNA test in London and has a brain scan in the USA to reveal the secret science of love. She also explores solo weddings in Japan, polyamory in South Africa and non-monogamy in LA.

The idea of gender is becoming more talked about. But what is it, and why does it matter? Cara explores drag with a trans man in LA, discovers a third gender culture in Mexico and experiences a ‘gender swap' in Spain. Along the way, she confronts her own gender fluidity and masculinity.

Porn is everywhere. But Cara discovers it isn't all bad. In Spain, she helps make an ethical, feminist porn film. She explores positive role models in gay porn in Germany, boy-on-boy love comics for women in Japan and sensitive, homemade porn in New York.

Cara grew up feeling ashamed of her sexuality. Now she wants to be out, loud and proud. In Germany, she meets queer refugees rebuilding their lives with cabaret, attends her first ever Pride in Tokyo and, in the US, parties at the biggest lesbian festival in the world.

Since men are having more fulfilling sex than women, Cara wants to find out why. She sets out to fix the so-called ‘orgasm gap'. In Germany she uncovers the science behind orgasms, makes 'vagina art' in Japan and dives into a masturbation class in New York and a women-only sex party in LA.
