Blog #23— Get To Know Mistrix Sunmi
Curious About Me? Get to know some intimate details about Me.
Who Is Mistrix Sunmi?
Mysterious? Serious? Funny?
It’s hard to truly get a feel for someone through a single ad, tweet, or blog post. Whether you’ve just discovered me or you're a devoted sub who already knows me well, this is a little window into who I am—a fun and personal introduction.
A Bit of My Cosmic Code
I’m a Taurus sun, Libra moon, and Virgo rising. Earthy, balanced, and always seeking order—yes, I absolutely live up to the astrology if you know you know.
Movement Is My Meditation
I’m a lifestyle Domme as much as I am a professional one. Physicality is central to who I am. I love long-distance running, biking, skateboarding, skiing, rollerskating, and surfing. If I can move my body, I’m happy.
I also went through a 35mm film photography phase, which taught me a lot about the art of capturing images—and, in turn, about modeling. Those skills still come in handy.
Music Is My Everything
Music has been a lifelong passion. Dance has been a lifelong joy. I spent my teen years at basement punk shows, summer festivals, and traveling to see my favorite bands live. A couple years ago, I picked up the electric guitar to deepen my relationship with music. These days, you’ll find me strumming sweet, cheesy beginner love songs—and loving every second of it.
Brain Food
I’m an avid reader, especially drawn to memoirs and books about death, dying, grief, the funeral industry, and global death traditions. It’s not as morbid as it sounds—there’s a profound beauty in how cultures honor life and loss. I lost my childhood best friend in a sudden death when we were 21, and her absence in my life changed my entire life tragectory.
Memoirs, especially, resonate with me because I’ve always been deeply interested in people. I crave real conversations, not small talk. I’ve never been one for shallow relationships—quality over quantity, always. That’s also why I love kink: it opens a space to explore deep, intimate truths and desires. It's about vulnerability, trust, transformation.
Yes, I’m Type A—And Proud
A friend once said, “Sunmi, you’re the most Type A person I know.” I laughed, but they’re not wrong.
I’m a clean freak. I like things done my way. I have high standards—for myself and my subs. I’m detail-oriented, meticulous, observant, and consistent. I fiercely protect my peace.
And yet, I’m also wholesome, kind, generous, goofy, and funny in my own way. I love people who can laugh with me and keep up with my standards.
A Forever Curious Mind
I love nerding out—on BDSM, kink gear, death, psychology, and more. With my ADHD, I’m always exploring new skills and hobbies to keep my brain engaged and my energy flowing.
I’m at my best when I’m using my hands or moving my body. That’s why rope and leather bondage, sissy training, electro, and single tails are some of my all-time favorite activities. They’re physical, emotional, sensual, and creative—just like me.
So, whether you’re here out of curiosity or deep devotion, welcome.

Blog #22— BiCostal Move
Bay Area & DC News!
I’m thrilled to share some exciting news: I’ll be relocating my home base from NYC to the Bay Area!
What Does This Mean for the Bay Area?
Starting mid-June, my books will open for in-person sessions in both San Francisco and Oakland. I can’t wait to connect with new and familiar faces on the West Coast.
What About DC Subs?
Good news—nothing changes for DC! Since moving to NYC, I’ve been touring DC every 4–8 weeks, and that routine will continue. DC remains my East Coast home base, so you can still expect me there once a month or every other month.
What About NYC Subs?
My NYC availability will decrease significantly. I’ll aim to visit every few months, but for those who can’t wait:
- FMTY to NYC is still an option.
- Or, you’re welcome to visit me during my DC tours if you'd like to see me sooner.
FAQ: Why the Move to California?
While I love NYC—and I’m grateful for the incredible friends and subs I’ve met here—it’s simply not a sustainable home for me long-term. After a year, I’ve realized I need a change of pace and energy, and the Bay Area feels like the right move.

Blog #21— So, You’re New To BDSM?
Mistrix Sunmi’s tangible & practical guide for BDSM newbies.

Are YOU fresh meat? My sincerest welcome!
You’ve come to the right place. BDSM can be very overwhelming and scary at first. There is a lot to learn, a lot to experience, and most likely, a lot of shame & fears to work through. Take a deep breath and pat yourself on the back. One of the biggest first steps is accepting that you’re kinky. Having a fetish or being drawn to playing with power exchange can often be a life-changing revelation. Let’s be honest, you’ve probably known that you’re kinky for a long time, but only now are you allowing yourself to explore it. It’s a natural journey we all go through. Our society is not always accepting, so it can be hard to admit, especially for those of us who have experienced trauma, were raised religious, and/or have taboo desires. Let’s dive in.
Connect with Yourself First
If you can, my advice is to always start within. It’s important to do self-reflection on your desires, limits, triggers, and fantasies. Before you play with someone else, take time to play with yourself. Through masturbation, reading erotica, watching porn, reading BDSM books, or talking to trusted friends, it’s important to connect with your mind and body to understand what turns you on.One of the things I LOVE most about BDSM is the consent culture. Here in kink, it provides a space where we can unapologetically state our wants, needs, and desires. BDSM is also a place where we do NOT have to do anything we do not want to do—i.e., our “hard limits.” Determining what you want or don’t want is especially hard when you are new. As a beginner, you may find that something you fantasize about may actually be unenjoyable or triggering when you act it out in real life. Or you may play with someone and not even realize you have a hard limit or trigger until you’re already in the middle of a scene. This is why playing with safe words is mandatory for beginners. There are a lot of emotional, physical, and spiritual risks in BDSM. It could open Pandora’s box, so it’s always my first recommendation to explore BDSM solo first.
How do you learn what you like or don’t like?
Learn about a wide variety of kinks. Explore on yourself— some examples: buy pink panties, hit your own balls, try anal on yourself, or tie a belt around your ankles just to see how it feels. Keep it low stakes, where you feel safe and comfortable. (I will say, DO NOT try breath play on yourself at home) Write down what turns you on AND what turns you off. This is valuable knowledge when you first start out, because there will be pressure on you once you “enter the scene” to self-identify. People will ask you for example, “so you are submissive? masochist? puppy?” People want to categorize you in community because they want to see if you two will be compatible or have kinks in common- ultimately it’s a way to bond or understand each other. It is perfectly okay to have no idea what you like—it’s all part of the journey. As someone who has been actively involved for almost 10 years, my sexual appetites change all the time—it keeps kink fun. The learning never ends.
Connect with Community
If you ARE able to attend in-person events or classes, I highly recommend connecting with your local community. Going to your first play party may be very nerve-wracking, but there is SO much to gain simply from going and voyeuristically watching. You will be amazed by how healing it can be for internalized kink shame to connect with others who share your kinks. Attend classes, support your local sex shops, and find online communities. I’ve always loved FetLife for finding events and connecting with kink groups. Follow me on FetLife HERE.Not everyone can or does have access to the “BDSM community.” BDSM isn’t always accessible to everyone. For example, classes can be expensive, dungeons may not be wheelchair accessible, and events may be too far away. If you’re only able to explore kink in private, or if you live in a small town, you may not be able to connect with or find play partners easily.
People hire pro-dommes for an endless number of reasons. One of the big reasons people book to play with me is that they may need discretion and privacy. Another reason is that I see folks with different disabilities, so they hire someone who is competent and nonjudgmental to play with. Or maybe you cannot find a play partner who is into or skilled in your more niche fetishes like medfet, ABDL, FTT or leather suspension. Most of all, a LOT of my subs who see me are exploring kink for the first time ever. I get a lot of BDSM virgins or newbies—these folks have entrusted me to provide a safe, nonjudgmental, and educational space for them to ease into their desires. If you do not have a clear idea of your desires, soft or hard limits, you can test them out with certified and trusted professionals who can expertly guide you through your first time. You can apply to play with me HERE.
Stay Safe & Have FUN
Kink is inherently risky. The dangers and unpredictability make it erotic, exciting, and FUN. The erotic thrill of putting your trust and submission into someone else’s hands is a huge act of bravery. There is SO much to gain from your first dive into kink. BDSM helps me uncover and reclaim my desires and my connection to my body and pleasure. The theatrical nature of roleplay and power exchange has transformed my life in ways that have empowered me in every area of my life. Be wary of a phenomenon called 'sub frenzy,' which occurs when people who are new to BDSM get so excited that they want to dive in too quickly. When you're new to the scene, you are the most inexperienced and, therefore, most vulnerable to being preyed upon by abusers. Aka people who know that you’re too new to even understand how to vet properly. Vetting is the process of getting to know someone before playing, asking for references, and learning about their community reputation to determine if they are a safe and compatible match to play with.
So, be careful, protect your sacred sexual energy, go slow, and use your safe words more than you think you need to.
Some final wisdom for submissives: As a person on this earth and as a submissive, you hold so much power. Handing control over to a trusted dominant and surrendering yourself is one of the most intimate things you can do. With the right fit, when you leave a scene, you should feel even more empowered than before. BDSM builds you up, no matter what end of the slash you are on. Your submission is a gift. Never forget that.

Blog #20— What Sets Me Apart From The Rest?
Sooo many dommes to choose from, why book Mistrix Sunmi? Here’s why.
I was recently told I don’t brag enough, and you know what? Maybe they’re right. So let me break it down for you. When you’re looking to invest in a new domme, it’s a big decision—intimate, expensive, and vulnerable. But here’s the thing: while there are plenty of amazing, ethical, and beautiful dommes out there, what sets ME, Mistrix Sunmi, apart from the rest?
It all comes down to expertise, chemistry and compatibility. Finding the right domme can sometimes feel like searching for a needle in a haystack. Trust me, I get it—because I feel the same way when I’m seeking subs to invest myself into. It’s about a connection that goes beyond the physical—something deeper, more personal, and absolutely irresistible.
So, what makes me different? Well, let’s start with my accomplishments and credentials.
From Passion to Profession:
I didn’t start out as a professional; I began as a lifestyle domme, driven by a genuine love for domination. It’s a passion that’s been with me for as long as I can remember—and I’d be dominating, whether money was involved or not. But when I decided to go pro, I wanted to do it right. So, I trained under Mistress Lina Lavender in 2019, a one-on-one mentorship that took me from the basics to advanced techniques like medfet, sissification, verbal humiliation, and much more. As a leather dyke, my experiences both in my personal and professional life have led to mastery of deepening erotic pleasure for folks of all genders and body types across the gender spectrum.
Psychology Meets Domination:
Since then, I’ve earned a Master’s degree in Psychology, a second degree that allows me to connect with my subs on a deeper level. This isn’t just about pleasure—it’s about guiding you through your submissive healing journey, helping you access pleasure like never before, and creating a space where you can truly embody your desires in a safe, profound way. This may be one reason why, several prodommes have hired me to help aid in their own pleasure journeys in a safe, non-judgemental, completely private space.
I believe that understanding the mind is just as important as understanding the body. By combining my psychology background with my domination skills, I create an experience that goes beyond just a scene—it’s a journey of transformation.
What sets me apart?
It’s my unwavering commitment to the craft and to you. I’ve spent years training, learning, and honing my skills, both inside the dungeon and outside of it. And it’s this combination of technical expertise, psychological insight, and genuine passion that allows me to create an experience that is truly one of a kind.
I’ve since taught numerous classes on topics I have mastered such as advanced needling/piercing play, connection to strap-on, sounding, building erotic ritual, single tail whipping and more. I also just completed my first ever domme mentee training program, where I passed on my knowledge on a one on one mentorship. As a life long learner in BDSM, I myself regularly attend BDSM classes, and hire professionals for one on one lessons. For example, in this past year I’ve had private lessons on erotic hypnosis and rope bondage from experts in the feild.
So, if you’re looking for someone who’s not just a pretty face or a well-trained domme, but someone who can connect with you on every level—physically, mentally, and emotionally—then maybe we should see if the chemistry is right.
Don’t believe me? Read my client testimonials HERE.
Will we have sexual chemistry?
Lets play a quick game - I’ll describe my style of domination and how I run things. If this turns you on, then we both win.
I expect full submission, and I accept nothing less. You hold a power within you. You surrender that power over to me, and I gladly take it with a seductive smile. I know how to wield your power against you. I’m aggressive. Hands on. Your autonomy leaves the second you walk through my door. You are prey, and I am an apex predator. I am muscular yet soft. I like my subs on their knees. Shaking, nervously for my touch. I gaze into your eyes, and I see right through you. I spread your legs. I invade your personal space with ease. I am rough, and I don’t hold back. Skillfully I always restrain you with careful consideration. I take your breath away, and I like it. I want more, so I take it. Hyper Focused, I notice your every wince, whimper, & moan. I feed off of you. My pleasure first. I love high fantasy - dark, perverted role plays, filthy sluts, suffering pain, erotic anticipation, psychological molding, intimate humiliation, and selfless worship - I am hedonistic. Lustful. I want it all. Now. And you can’t resist.
