Sex education does not end when we turn 18. In fact, adulthood is often when we begin to understand our bodies, explore relationships, and ask questions about intimacy, desire, consent, and sexual health. Yet, many people still find these subjects difficult to discuss openly.
Films can help make these conversations easier. Through documentaries and thought-provoking stories, we can learn about sexual well-being, recognise unhealthy expectations, and understand why communication matters in intimate relationships.
While movies cannot replace reliable medical advice, they can offer valuable perspectives on real-life experiences. Here are eight films and documentary series worth watching if you want to explore sex education beyond the basics.
The Principles of Pleasure (2022)
Best for: Understanding female pleasure and sexual well-being
Pleasure is an important part of sexual well-being, yet it is often overlooked in traditional conversations about sex. The Principles of Pleasure is a documentary series that explores female sexuality through science, personal experiences, and expert insights.
It examines how the body responds to pleasure, challenges common misconceptions about orgasms, and explores the influence of culture and social expectations on women’s experiences of sex.
The series also encourages viewers to question the idea that intimacy should follow a particular script. Everyone experiences pleasure differently, and understanding those differences can help people feel more confident about their bodies.
What you can learn: Sexual pleasure is a normal aspect of well-being, and understanding your body can help you communicate your needs more confidently.
Sex, Explained (2020)
Best for: Learning the science behind sex
If you prefer straightforward information presented in an accessible format, Sex, Explained is a useful place to start. This documentary series explores different aspects of human sexuality, attraction, fertility, and sexual fantasies.
It breaks down complicated topics into easy-to-understand explanations, helping viewers separate scientific information from common myths.
For adults who did not receive comprehensive sex education growing up, the series can introduce subjects that may otherwise feel uncomfortable to discuss. It also highlights how biology, psychology, and personal experiences can shape our understanding of sexuality.
Of course, not every question about sexual health can be answered by a television series. However, it can encourage viewers to seek accurate information and become more comfortable asking questions.
What you can learn: Understanding the science behind sexuality can help you make informed decisions about your body and relationships.
The Little Death (2014)
Best for: Exploring sexual fantasies and communication
Sexuality is not identical for everyone. People have different preferences, boundaries, and ideas about intimacy, and understanding these differences is an important part of building healthy relationships.
The Australian comedy The Little Death explores the private sexual lives of several couples, using humor to examine fantasies, awkward conversations, and the challenges people face when discussing their desires.
Although the film is fictional and sometimes deliberately uncomfortable, it opens up conversations about subjects that couples may find difficult to raise themselves.
Its central themes remind viewers that assumptions can create misunderstandings. Partners may have different expectations, and honest conversations can help them understand one another.
Importantly, having a fantasy does not mean someone must act on it. Any exploration of intimacy should involve freely given consent, mutual respect, and clear boundaries.
What you can learn: Open communication about preferences and boundaries can help partners build trust without pressure or judgement.
Good Luck to You, Leo Grande (2022)
Best for: Sexual confidence and discovering pleasure
Sexual confidence is not something everyone automatically develops with age. For some people, it takes time to understand their desires, challenge social expectations, and feel comfortable discussing intimacy.
Good Luck to You, Leo Grande follows Nancy, a retired teacher who seeks new experiences and a better understanding of her sexuality. Through her conversations with Leo, she begins questioning the beliefs she has carried about her body, pleasure, and what it means to feel fulfilled.
The film explores vulnerability, ageing, body image, and the emotional side of sexual discovery. It also shows how difficult it can be to move beyond embarrassment when discussing personal desires.
Rather than presenting intimacy as something that should look a particular way, the story encourages a more thoughtful approach to self-discovery.
What you can learn: Sexual confidence can develop at any age, and understanding your needs begins with giving yourself permission to explore them without shame.
The Sessions (2012)
Best for: Understanding intimacy and disability
Conversations about sex education should include people with different bodies, abilities, and experiences. However, disability and sexuality are often left out of mainstream discussions.
The Sessions tells the story of Mark O’Brien, a poet who lives with the effects of polio and uses an iron lung. With support from people around him, he explores intimacy and the possibility of experiencing a sexual relationship.
The film approaches the subject with sensitivity and humor, challenging assumptions about disability, independence, and desire.
It also illustrates that intimacy involves more than physical attraction. Emotional connection, communication, trust, and feeling respected can all play important roles in a person’s experience of sexuality.
The story is not a guide to sexual health, but it offers an opportunity to reflect on how narrow social expectations can influence our understanding of relationships.
What you can learn: Sexuality and the desire for connection are not limited to one type of body or one way of experiencing intimacy.
Ask Me Anything (2014)
Best for: Exploring relationships and personal boundaries
Growing up involves making decisions about relationships, attraction, and personal identity. It can also mean navigating conflicting advice from friends, partners, and society.
Ask Me Anything follows a young woman who begins documenting her experiences and reflections while navigating relationships and the uncertainties of early adulthood.
Although the film is not a formal sex education resource, it explores the complicated emotions that can accompany attraction, vulnerability, and personal choices.
For adult viewers, it can prompt questions about how we decide what feels right for us, how much influence other people’s opinions should have, and why recognising personal boundaries matters.
It is also a reminder that experiences portrayed on screen do not always represent healthy behaviour. Viewers should reflect critically on the choices characters make rather than treating every situation as an example to follow.
What you can learn: Understanding your own values and boundaries can help you make more thoughtful decisions about relationships and intimacy.
How to Have Sex (2023)
Best for: Consent, peer pressure, and sexual expectations
Consent is one of the most important parts of sex education, but understanding it involves more than knowing the definition. It also means recognising pressure, respecting boundaries, and understanding that people can change their minds.
How to Have Sex follows three British teenagers on a holiday that becomes a difficult experience of friendship, expectations, and sexual pressure.
Although the characters are younger than the film’s adult audience, its themes are relevant to anyone navigating intimacy. The story examines how the desire to fit in can affect decisions and how social expectations can make it harder to express discomfort.
It also encourages viewers to consider the difference between wanting an experience and feeling that they are expected to have it.
Healthy consent must be freely given, specific, and ongoing. Silence, uncertainty, or pressure should never be treated as agreement.
What you can learn: You never owe anyone sexual access to your body, and a respectful partner will accept your boundaries without coercion.
The Principles of Pleasure and Real-World Sex Education: What to Watch Next
For viewers who want to go beyond fictional stories, revisiting The Principles of Pleasure alongside reliable sexual-health resources can be a valuable next step.
The documentary series provides a foundation for thinking about pleasure, anatomy, and cultural attitudes towards sexuality. You can build on those ideas by exploring evidence-based information about contraception, sexually transmitted infections (STIs), reproductive health, and communication.
Resources from organisations such as the World Health Organization and NHS can help answer practical questions that films may not cover in enough detail.
This combination matters because sexual well-being involves more than understanding attraction or pleasure. It also includes protecting your health, making informed choices, and recognising when professional advice is needed.
What you can learn: Entertainment can open the conversation, but accurate information helps you make safer and more informed decisions.
What These Films Teach Us About Sex Education After 18
Sex education in adulthood is about much more than learning the mechanics of sex. It involves understanding our bodies, respecting other people’s boundaries, communicating honestly, and making decisions that reflect our needs and values.
These films approach sexuality from different perspectives. Some focus on the science of pleasure, while others explore the emotional realities of relationships, the importance of consent, and the assumptions that shape our experiences.
However, it is important to remember that films are not all equally educational. Documentaries can introduce useful information, while fictional stories often serve as starting points for reflection and discussion.
Ultimately, healthy intimacy does not follow a universal formula. It depends on mutual respect, informed choices, emotional comfort, and the freedom to say yes, no, or not yet.
The more openly we discuss these subjects, the easier it becomes to replace shame and misinformation with confidence and understanding.
