How to teach a person with autism about privacy, bodily boundaries, and consent

Some things should be learned before a problem arises.

Imagine a relative wants to greet an autistic person with a hug. The person pulls away, but someone insists:

"Give him a hug—he’s your uncle."

In another scenario, someone might walk into a room while another person is changing clothes, simply because they do not understand the need for privacy.

It is also possible that someone might ask an autistic person to keep a secret about physical contact that made them uncomfortable, leaving them unsure whether they should tell their family.

These are different situations, but they share a common thread: the individual needs to understand rules regarding their own body, their personal privacy, and respect for others.

These skills are not always learned spontaneously through observation. Some autistic people may require more direct explanations, concrete examples, and opportunities to practice situations that others might learn about informally.

For this reason, teaching bodily privacy and consent should not begin only after an incident has occurred.

It should be part of everyday learning, tailored to each person’s age, abilities, and needs.

The goal is not to frighten the individual or lead them to believe that all physical contact is dangerous.

Rather, the goal is to help them understand three fundamental concepts:

- My body deserves respect.

- Other people’s bodies also deserve respect.

- I can ask for help when something makes me uncomfortable or when I do not understand what is happening.

1. Teach the names of body parts clearly and naturally.

A person needs to know their own body in order to communicate discomfort, ask questions, and explain situations that worry them.

Use the correct names for body parts—including the genitals—using language appropriate for the person’s age and level of understanding.

There is no need to turn every conversation into a formal lesson.

You can take advantage of everyday moments, such as getting dressed, bathing, or talking about a doctor’s appointment.

For example:

"This part of your body is called a shoulder." “This part is called the abdomen.”

“The penis and the vulva are also parts of the body, and we can talk about them naturally.”

These explanations can be supported by age-appropriate anatomical illustrations, educational books, or reliable visual materials.

Avoid conveying the idea that certain body parts are dirty or shameful. A person should be able to name them in order to discuss health, hygiene, and safety, without fear of being reprimanded.

Knowing one’s own body is a tool for autonomy—not an invitation to feel shame.

2. Explain what privacy means using concrete situations

Saying "you should have more privacy" can be too abstract.

It is more helpful to explain what privacy means in real-life situations.

For example:

In the bedroom: knocking on the door before entering and waiting for a response whenever possible.

In the bathroom: closing the door when using the toilet or changing clothes, provided the person can do so safely.

When getting dressed: finding an appropriate space to take off or put on clothing.

When discussing personal matters: choosing who to share private information with.

Not all situations are the same. A person might need assistance with dressing or personal hygiene; this should be explained in a tailored way that respects their dignity and encourages their participation.

Instead of teaching a rule like "no one is ever allowed to enter," explain common scenarios and the exceptions related to necessary assistance, health, and safety.

You can use a visual aid with two columns:

PRIVATE — BEDROOM, BATHROOM, CHANGING CLOTHES

SHARED SPACES — LIVING ROOM, KITCHEN, CLASSROOM

Then, adapt these examples to the places the person frequents.

3. Teach them that they can say no to a hug

Many families take it for granted that hugs, kisses, or affectionate touches are mandatory expressions of love.

However, caring for someone does not mean having to accept all forms of physical contact.

A person might enjoy hugs at certain times but decline them at others. They might also prefer to greet others with a handshake, a high-five, a smile, or simply by saying "hello."

Teach them simple phrases such as:

- "I don't want a hug."

- "I’d rather shake hands."

- "I need some space."

- "Not right now, thanks."

You can also practice using gestures or visual cards if speaking is difficult for them. But there is a second, equally important lesson: when someone else says they do not want a hug, we must respect that, too.

The rule must work both ways.

We should not force anyone to accept physical contact just to avoid offending someone else, nor should we allow anyone to touch others without respecting their boundaries.

4. Explain consent using everyday examples

Consent means understanding that a person can accept or decline an interaction, and that their decision must be respected.

There is no need to start with complex definitions.

You can teach this concept through common, everyday situations.

Example 1: A hug

Ask: "Would you like a hug?"

Wait for the response and respect it.

Example 2: Taking a photograph

Ask before taking or sharing a photograph, taking into account the person’s level of understanding and the specific circumstances.

Example 3: Helping with dressing

Explain what kind of help you are going to offer, and allow the person to participate and express their preferences.

Example 4: Touching personal belongings

Teach the person to ask before picking up someone else’s phone, backpack, or other personal items.

These rules can be adapted to the language or communication style that the person understands best.

The key is for the person to learn that decisions should not be made automatically on their behalf, and conversely, that they should not always make decisions for others without considering the other person’s input.

In situations involving healthcare, hygiene, or safety, physical intervention may be necessary. In such cases, it is important to explain what is going to happen, respect the person’s privacy, and encourage their participation whenever possible.

5. Help the person distinguish between accepted contact, uncomfortable contact, and contact that requires seeking help

Teaching only that "people you know are safe" may not be sufficient.

Someone you know might still cross a boundary, while a healthcare professional might need to perform a legitimate examination—provided that the appropriate explanations, safeguards, and consent or authorizations are in place.

It is better to teach the person how to evaluate the situation.

You can explain three concepts:

Accepted contact: Both individuals agree to the contact.

Unwanted contact: Someone touches or approaches in a way that the other person does not want, even if there is no intent to cause harm.

Unsafe contact: A situation that involves harm, pressure, exploitation, or a violation of personal boundaries. Clarify that the person can step away, ask for contact to stop, or seek help whenever they feel uncomfortable.

They also need to understand that any contact necessary for medical care or personal assistance must be clearly explained, carried out with respect for their dignity, and aligned with applicable requirements and safeguards.

It is not necessary for them to be able to perfectly categorize every situation. What matters is that they know they can express discomfort and share what happened with someone they trust.

6. Teach them which body parts are private and what that privacy means.

Explanations should be clear, age-appropriate, and consistent with the guidance provided at home and at school.

You can explain that the areas typically covered by underwear are private and that no one should touch them for sexual reasons without consent. It is also important to address necessary exceptions—such as those for medical care, hygiene, or personal assistance—while providing appropriate explanations and safeguards.

Avoid setting absolute rules that could cause confusion, such as "no one is ever allowed to touch you there," as the person might need help with personal hygiene or medical care.

Instead, teach these concepts:

- My body belongs to me.

- I can ask why someone needs to help me.

- I can express discomfort.

- If I don’t understand a situation, I can turn to a trusted person.

- If someone makes me feel unsafe, I can tell someone, even if they asked me to keep it a secret.

It is important to revisit these rules on various occasions and verify that the person truly understands them, rather than simply asking, "Do you understand?"

7. Distinguish between secrets, surprises, and private information.

This distinction can be especially helpful in protecting someone from manipulative situations.

Someone might say to them:

"Don't tell your family what happened."

The person needs to know that they are under no obligation to keep a secret about something that causes them fear, pain, shame, or a sense of being unsafe.

You can teach them this phrase:

"If someone asks me to keep a secret about my body or something that makes me feel bad, I can tell a trusted person."

It is also helpful to explain that some information is private—such as a password or medical details—while clarifying that privacy is not the same as hiding dangerous situations.

A pleasant surprise, like a birthday gift, is different from a secret used to prevent someone from seeking help.

Use simple examples, and avoid causing fear through threatening stories.

8. Create a list of people they can turn to

Simply saying "ask for help" is not always enough.

The person needs to identify who they can turn to and what they can say.

You can create a card listing two or three trusted individuals, tailored to their specific situation.

For example:

PEOPLE I CAN TALK TO

- My parent or caregiver.

- My trusted teacher.

- Another trusted adult.

The card can include photographs, names, and contact information for these individuals—while always ensuring personal information remains protected.

Teach them when to use it by providing examples:

"If someone touches you and you don’t want them to, you can move away—if it’s safe to do so—and tell me."

"If someone asks you not to tell anyone about something that scares you, you can talk to me."

"If you don’t know what to do, you can ask for help."

Avoid relying on just one person for safety; it is better for them to be able to identify several appropriate options.

9. Practice how to respond, rather than just memorizing a single phrase

A person might memorize the phrase "say no," yet freeze up when faced with a real-life situation.

Therefore, it is helpful to practice everyday scenarios—without causing fear or setting "surprise tests."

For example:

Situation: Someone wants to give them a hug.

Possible response: "I don’t want a hug; I’d prefer to just wave hello."

Situation: Someone takes their phone without permission.

Possible response: "That’s my phone. Please give it back."

Situation: They don’t understand why a professional needs to examine them.

Possible response: "Please explain to me what you are going to do and why."

You can use drawings, social stories, dolls, or simple role-playing games.

Afterward, ask what they might do in a similar situation, and be open to different ways of responding.

The goal is not for them to recite a perfect script, but rather to develop the tools to communicate their boundaries and seek help.

10. If someone invades another person’s space, teach a specific alternative

Some individuals may get very close, touch someone’s hair, take personal belongings, or offer hugs without asking.

It is best not to automatically assume that they are doing so to be bothersome.

They may not have learned a specific social rule, they might be seeking sensory input, or they may simply not know how to initiate an interaction.

The response should protect the other person while also teaching an alternative behavior.

Instead of simply saying:

“Don’t do that!”

You could say:

“First, ask if you can touch their hair.”

Or:

“Before giving a hug, ask: ‘Would you like a hug?’”

If the other person says no, teach the individual to stop.

If there is an immediate risk, intervene to ensure safety, and then practice the skill later when things are calm.

Understanding the reason behind a behavior does not mean allowing the boundaries of others to be violated. It means choosing an approach to teaching that can truly be helpful.

11. Coordinate explanations between family members and professionals

An individual may receive conflicting messages at home, at school, and during community activities.

For example, one person might tell them they must accept kisses from relatives, while another teaches them that they have the right to decline.

Such contradictions make learning difficult.

Whenever possible, reach an agreement with those involved in the individual’s education regarding common rules for:

- Bodily privacy.

- Physical contact and consent.

- How to ask for help.

- What to do in an uncomfortable situation.

- How to respect personal space.

- The language to use when explaining these rules.

The vocabulary and support materials used should be accessible to the individual and appropriate for their age and level of understanding.

12. Do not turn body education into a source of shame

A person might ask a question about their body at an unexpected moment or show curiosity about physical differences.

The response should never be to humiliate them or label their question as "dirty."

You can answer briefly and directly:

"That’s a question about the body. We can talk about it, and I will explain it using words you can understand."

If the topic requires more privacy:

"That’s an important question. Let’s talk about it in a quiet place."

Afterward, follow through on your promise. Avoid leaving their questions unanswered or making them feel as though they cannot talk about their body.

Body education is most effective when a person knows they can ask questions and receive honest, appropriate, and respectful information.

13. Observe how they understand the information, rather than just whether they repeat the words

A person might repeat the phrase "my body belongs to me" without truly grasping what it means in an everyday situation.

Therefore, use examples and observe how they apply them.

You might ask:

"If someone wants to give you a hug, but you don’t want one, what can you do?"

Follow up with:

"If a friend doesn’t want to be hugged, what should we do?"

Or:

"If someone asks you to keep a secret that makes you feel unsafe, who can you tell?"

Accept responses given through words, gestures, drawings, or the person’s usual method of communication.

If they need help, explain it in a different way and practice again later.

Learning should be evaluated based on understanding and the ability to apply a skill, not merely on the memorization of a phrase.

14. What to do if you are concerned that someone’s boundaries have been violated

If a person shares that someone has touched them inappropriately, pressured them, or asked them to keep a secret regarding their body, listen calmly.

Thank them for telling you.

Avoid blaming them, questioning them repeatedly, or asking leading questions that suggest a specific answer.

Do not promise to keep a secret about a situation that may require protection.

If there is an immediate risk, prioritize the person’s safety. When there are signs of abuse or exploitation, seek help from the appropriate professional and protective services in your area.

A change in behavior does not, by itself, prove that abuse has occurred; however, any disclosure or specific concern must be taken seriously and handled with care.

In such situations, it is not the responsibility of an autistic person to prevent all abusive behavior on their own—adults and institutions must implement the necessary protective measures.

An activity to try at home: "My Body, My Choices"

You can carry out this activity during a quiet moment, breaking it down into three parts.

PART 1: MY PREFERENCES

Ask which forms of greeting the person enjoys and which ones they prefer to avoid.

They can point to images, choose a card, or respond verbally.

PART 2: OTHERS' BOUNDARIES

Present simple examples regarding asking for permission before hugging, taking an object, or touching someone else.

PART 3: HOW TO ASK FOR HELP

Review who the person’s trusted individuals are, and practice using a phrase, gesture, or card to communicate when a situation feels uncomfortable.

You do not need to complete the activity in a single session. You can break it into smaller segments and revisit these skills whenever appropriate.

The goal is for the person to understand the concepts, not to memorize a list just to please the adults.

When should you seek professional support? If there are significant difficulties in understanding privacy, communicating boundaries, recognizing unsafe situations, or respecting the personal space of others, it may be helpful to seek guidance from a professional with expertise in autism and sex education.

A professional can adapt materials to suit the individual’s age, level of understanding, communication system, and specific needs.

If you suspect that abuse, exploitation, or a violation of rights has occurred, seek support from the appropriate healthcare or protective services. Do not wait until an educational program is completed before taking action.

The most important things an autistic person should learn about their own body

There is no need to memorize an endless list of prohibitions.

What is needed is an understanding that one can express preferences, decline unwanted contact, respect the boundaries of others, and ask for help when something feels confusing or unsafe.

It is also important to know that one can ask questions about one’s own body without being made to feel ashamed, and receive information that is easy to understand.

Teaching privacy does not mean instilling fear. Teaching consent does not mean eliminating affection. Teaching boundaries means providing tools for interacting with greater safety, respect, and autonomy.

Perhaps the most important change begins at home: when we stop demanding that someone accept an interaction out of obligation, and instead begin teaching them that their own preferences also deserve to be heard.

Frequently asked questions about body privacy and autism

How can I teach an autistic person to say "no" to a hug?

Practice using phrases, gestures, or cards that can be applied in real-life situations. Respect their own refusals, and also teach them that they must respect the "no" of others.

How do I explain which parts of the body are private?

Use correct terminology, age-appropriate visual materials, and everyday examples—such as getting dressed, using the restroom, or receiving assistance with personal care. Also, explain exceptions related to medical care or necessary personal assistance.

Is it helpful to teach these skills using images?

Photographs, illustrations, social stories, and visual sequences can make concepts easier to understand. Tailor the materials to the way the individual processes information and communicates.

What should I do if they touch others without asking for permission?

Intervene when necessary to ensure safety, clearly explain the boundary, and teach a specific alternative—such as asking before touching. Practice this skill without causing the person to feel humiliated.

How can I help them recognize an unsafe situation?

Provide clear examples, teach them how to express discomfort, show them who to turn to, and explain how to ask for help. They do not need to be able to identify every situation on their own; protection from adults and professionals remains essential.
