A Parent’s Guide to Understanding Adolescent Sexuality Development

As a parent, watching your child grow is one of the most beautiful and, at times, most challenging parts of life. Among the many areas of development, from learning to walk and talk to discovering passions and talents, is their journey in understanding their own sexuality. This can bring up a lot of questions for both you and your child.

Let’s walk through what this process can look like, with warmth, clarity, and compassion. This guide will help you understand the basics of sexuality, sexual identity, sexual orientation, and sexual expression, and how these aspects may naturally evolve during childhood and adolescence.

You’ll find more information about sex education in my Sex Education 101 page.

Let’s get started!

First Things First: What Is Sexuality?

Sexuality is a broad term that includes emotional, romantic, and physical attraction, as well as a person’s sense of identity related to gender and sexual orientation. It’s more than just sex — it’s about relationships, intimacy, self-image, and how one expresses love and affection.

Sexuality isn’t something that appears all at once. It develops in stages, often gradually, and is influenced by a mix of biology, environment, culture, family values, and personal experiences.

Early Childhood (Ages 0–5): Innocent Curiosity

At this age, children are not sexual in the adult sense, but they are developing an understanding of their bodies, relationships, and affection.

What to Expect:

• Curiosity about their own bodies and the differences between others.
• Mimicking behaviour (like kissing or holding hands) they see in adults.
• Questions like “Where do babies come from?”
• Affectionate behaviour and attachment to caregivers.

How to Support:

• Normalise their curiosity without shame.
• Use the correct names for body parts.
• Respond calmly to questions, using age-appropriate language.
• Foster body autonomy by teaching them that they can say “no” to unwanted touch – even from relatives!

Middle Childhood (Ages 6–11): Learning and Labelling

Children start to become more aware of social norms, gender roles, and family values. They may begin to notice attraction, but it’s often more emotional than physical at this age.

What to Expect:

• Forming deeper friendships and preferences for same-gender or opposite-gender play.
• Increased interest in how bodies change (especially as puberty nears).
• Early feelings of romantic interest often expressed as crushes.
• Some children may begin to question their gender or orientation.

How to Support:

• Reassure them that all feelings are normal.
• Encourage open conversations about feelings and friendships.
• Discuss puberty ahead of time so they’re prepared (not scared).
• Use inclusive language when talking about relationships (“when you have a partner” instead of “when you get a boyfriend/girlfriend”).

Tween & Early Teens (Ages 12–14): Puberty and Exploration

Puberty kicks in, and with it comes big changes physically, emotionally, and socially. Sexuality becomes more present and can be a source of excitement or confusion.

What to Expect:

• Physical changes (e.g., menstruation, erections, body hair).
• Stronger interest in dating or attraction.
• Identity exploration, including gender and sexual orientation.
• Some tweens may come out as LGBTQIA+ while others may still be questioning.

How to Support:

• Offer age-appropriate resources or books about identity and relationships.
• Be a safe, judgment-free zone for questions or feelings.
• Let them know that exploring and questioning their identity is completely normal.
• Avoid assumptions. For example, don’t assume they’re straight or cisgender because it’s the “expected norm”.

Later Teens (Ages 15–19): Identity and Expression

As teens mature, they often become more comfortable expressing who they are and forming deeper romantic relationships.

What to Expect:

• Defining sexual orientation and possibly coming out.
• Developing a sense of gender identity and personal style.
• Experimenting with sexual expression in safe or risky ways.
• Forming more serious romantic or intimate relationships.

How to Support:

• Respect their privacy but remain a trusted resource.
• Keep communication open and nonjudgmental, even when it’s uncomfortable!
• Talk about consent, safety, and respect in all relationships.
• Support their expression (clothing, pronouns, etc.).

Understanding the Terms

Here’s a quick glossary to help you feel confident in conversations:

• Sexual Identity: The labels and language someone uses to describe their orientation, gender, and sexual self (e.g., “I’m a lesbian” or “I’m queer”).
• Sexual Orientation: Who a person is emotionally, romantically, or sexually attracted to (e.g., gay, straight, bisexual, asexual).
• Gender Identity: A person’s internal sense of being male, female, both, neither, or somewhere in between.
• Sexual Expression: How someone expresses their sexuality — through clothing, behaviour, relationships, etc.

Your Role as a Parent

Contrary to popular belief, you don’t need all the answers! What your child or teen needs most is:

• Validation: Let them know that who they are is okay and loved.
• Support: Be their advocate in a world that might not always understand them.
• Boundaries and Guidance: Teach them about healthy relationships, communication, and respect.
• Openness: Create space for honest, evolving conversations — it’s okay not to know everything!

Helpful Resources

• Children’s books about being LGBTQ
• PFLAG – Support for LGBTQ+ individuals and their families
• Sex Positive Families – Talking to kids about sex and relationships
• Planned Parenthood’s Resources for Parents

Final thoughts

Your child’s sexuality is just one part of who they are, and it’s okay if it takes time for them (or you) to understand it. What matters most is that they feel seen, accepted, and loved unconditionally. Stay curious. Stay open. You’re doing a great job! And remember – no one has all the answers, but together, we can create a kinder, more inclusive world for our kids to grow up in.
