BDSM and kink explained: consent, boundaries and how to start

With Mistress Anastasia — professional dominatrix and kink educator

Most of what people believe about BDSM is wrong, and the misunderstanding stops at the first question: BDSM and kink are not the same thing. In this episode, Mistress Anastasia explains the difference, how consent is actually negotiated, why claiming to have no limits is a warning sign rather than an invitation, and how to raise any of this with a partner.

A note before you read. This conversation is intended for adults and discusses sexuality, consent and kink openly. It is general discussion only — not medical, psychological or therapeutic advice, and not an offer or advertisement of services. Anything described here assumes informed, enthusiastic consent between adults. Views expressed by guests are their own.

Key takeaways

  • Kink is the broad term. BDSM is one part of it, and most kinks are not BDSM.
  • Safe, sane, consensual and legal is the standard everything is measured against.
  • Negotiation happens before, not during. What is agreed at the start is what happens.
  • "I have no limits" is a red flag, not an invitation.
  • Raise it outside the bedroom. Springing something mid-session is the wrong moment.
  • Physical cues matter as much as verbal ones — leaning in and pulling away both mean something.
  • A technique that worked with one person may not work with the next. Ask.
  • Labels are useful and also temporary. Identifying as something now does not commit you to it forever.
  • Most kinks have a traceable origin, and understanding where yours came from is generally a healthy sign.
  • If you do not know how to do something safely, learn from someone who does.

BDSM and kink are not the same thing

MJ: Do people put BDSM and kink in the same basket?

Anastasia: I always like to separate the two. Kink is a broader way to describe what we would be doing. BDSM traditionally stands for bondage, discipline, dominance, submission, sadism, masochism — there are a lot of variations on that. But kink can be anything, from foot fetishes to all different kinds of fetishes.

The terms, briefly

Kink
The umbrella term for any specific sexual interest outside the conventional. Does not require power exchange.
BDSM
Bondage, discipline, dominance, submission, sadism, masochism. A subset of kink involving power exchange.
Dominant / submissive
A psychological dynamic. Does not necessarily involve sex at all.
Top / bottom
Describes who is doing and who is receiving in a given act. Related to but distinct from dominance.

Different strokes for different folks. As long as it is safe, consensual, sane and not illegal, you are good.

The most common misconception

Anastasia: Society often thinks BDSM and kink are very taboo, and that people are doing it against their will. With something like impact play, people think — well, you are getting hit, how can you like that?

She points to the obvious answer: the line between pleasure and pain is a real thing, and it sits differently for different people. Education is what closes the gap.

How consent is actually negotiated

The part most people get wrong is timing. Consent is not a single yes at the start of an evening — it is a specific agreement about specific activities, reached before anything begins.

Anastasia: It is always good to negotiate what is and is not okay at the start. Because often when you are playing, you might get halfway through and something will change — and if that was not negotiated at the start, you really should not be proceeding with it.

Anastasia: Generally speaking, what is agreed at the start is what happens, and nothing further. If you want to go further, next time you can. You just have to have a second date.

Established partners may have more latitude, but the principle holds: new territory is a new conversation.

Why "no limits" is a red flag

Anastasia: If people come to me and say I have no boundaries, I have no limits, that is a red flag. That is when you can injure someone. Or maybe they are not saying what they actually mean.

It is healthy to have boundaries — not only in kink but in life. Someone who claims none has either not thought about it or is not being honest, and both are risks.

How to raise it with a partner

This is the question Anastasia says comes up most often, both from clients and from people in sex toy stores: I am into this, my partner is not, what do I do.

Anastasia: Sometimes you just have to get some courage and say — hey look, I want to have a conversation with you about what I am feeling sexually, and some things I would like to try, and I hope you are open-minded enough to hear me out. Because if you do not say it, they are not going to know.

Anastasia: You should not spring it on them mid-session either.

If you are flying through a relationship and never having hard conversations, are you really being your authentic self? Are you really learning about your partner?

She notes that these conversations can be genuinely difficult — people cry, people disagree — and that a counsellor or therapist can help if it is not going well alone.

Role play, and why routine kills desire

Anastasia describes working with a couple whose dynamic had become fixed: he was always dominant, she was always submissive, and he wanted the reverse. The session was largely about giving her permission to try a role she had never occupied.

For couples stuck in domestic roles, her recommendation is to leave the house entirely.

Anastasia: I am always advocating a hotel room. If you have kids, get a babysitter. Do what they do in the movies — go to a bar and pretend you have never met before. Get some nice lingerie. A suit. Push the boundaries a little.

Anastasia: When you are living with your partner you get into a bit of a rut. He might see her as the mother, doing everything for the kids, and he is going to work. Stepping out of that will reignite the spark.

Listening, verbal and physical

MJ: Sometimes people go in very confident, thinking they know everything.

Anastasia: It is really hard if someone goes into sex super confident and is not listening to the other person. And listening is verbal, but also physical. If someone is leaning into you, that means something. If someone is pulling away, that means something too.

For anyone who cannot easily speak in the moment, she suggests agreeing a physical signal in advance — a tap on the leg, for instance — so feedback is possible without needing words.

MJ: Your technique might not work for every woman. You have to be open to understanding yourself and the other person.

Anastasia's point, illustrated with a story about two very different experiences, is that no technique transfers cleanly between people. What worked spectacularly once can fall flat next time, and the only reliable method is asking.

Labels are useful and temporary

Anastasia: There are a lot of labels within the community. Sometimes you might identify as one thing, and that is okay. But it is also okay in twelve months to want to change it. Never feel that putting a label on something means you cannot evolve.

She describes her own shift — predominantly submissive in her early twenties, predominantly dominant now — as an ordinary example of interests changing with time.

Exploring your sexuality isn't black and white. It's colourful. It's exciting, emotional, passionate.

Where kinks come from

One of the more interesting threads is the origin of specific interests. Anastasia describes disliking having her feet touched when younger — the result of an offhand childhood joke that left her believing something was wrong with them — and how foot work later became something she enjoys.

Anastasia: With kink it all derives from somewhere, generally. And if you can identify that, it is usually a healthy sign that you are doing things right.

Learning safely

Anastasia: If you do not know how to do something, you can hire a professional to guide you through. There are podcasts, blogs, a lot of content out there — but do not necessarily take it verbatim.

She notes that in most major Australian cities there are established communities running classes and safe spaces for people learning.

  • Research the specific thing before trying it
  • Learn from people with experience rather than improvising
  • Preparation is part of safety, not an afterthought
  • Public activity is not consensual for the people around you

On shame

The episode closes on a card drawn from a conversation deck: in what way do you feel ashamed or guilty around sex?

Anastasia describes a recent conversation with someone close to her who felt he was performing a version of himself his family expected — about work, identity, sexuality — and traced it back to generational patterns.

Anastasia: I asked him: what do you want the world to see you as when you are gone? How do you want people to remember you?

Anastasia: If I want people to remember me, I want them to say that was the one who tried to help people with sex, and educate them about safe and consensual sex.

Anastasia: Stop trying to live someone else's life. Figure out what your life is, and then you will not have shame.
