If only we knew what the "gilded explorations" promised on Boehm's website actually involved."What I do isn't the same as being a relationship counsellor," Boehm tells me, and although the Austrian accent makes her sound severe and wise, her expression is warm and open.
To be crystal clear, she's "not a sex coach", either.
"I don't watch people have sex or tell them what to do. My work is about looking at a relationship and helping you to invest time in making it work, which is crucial. Because nobody would hand you a million dollars without first giving you financial help, would they? And a relationship is worth more than that."
Boehm works with everyone from the biggest entertainers in the world ("one client was so famous, I had to be taken to them under a blanket") to "those who potter in off the street" to attend the £400-plus workshops she gives all over the world.
However, she feels her "skill set lends itself to working for people who are high-performance". And, let's face it, they need her.
What is it that makes it so hard for the rich and famous to stay happy and married - let alone both?
"Well, the two sectors contain people who are extremely high-performing in many areas of their lives," she says.
"So that when they have 'leaks', as I call them - and I mean leaks of energy or compassion - they are often in relationship and sex areas."
Famous men are having a particularly difficult time of it right now, she believes. "Because it's so dangerous for them - and they can be preyed upon. Nobody talks about that. Everybody talks about MeToo, which is valid and important, but there is a whole other dark side where men are getting trapped and blackmailed. Gossip alone can be very damaging."
Accomplished and powerful "have it all" women like Paltrow don't have it easy either.
"They can't date quietly", let alone "deal with heartbreak and insecurities" - and she is in awe of her client's openness.
"Gwyneth has exposed herself to some pretty brutal criticism, but people are understanding what a role model she is. Her commitment to love in the greater picture, and the wellbeing of her children and everyone involved, including the exes of the exes, isn't something to sneer at - it's admirable."
This is true. And perhaps now that people have seen the important point behind the "conscious uncoupling" jargon, they may follow the actress's lead?
"I hope so. Because someone like her can make an impact by making a statement that is out of the ordinary. And just as she showed that there is a better way to divorce, perhaps we can now show people that there is another way to have relationships."
Whether you're an A-lister or not, the rules are the same once lessons begin.
"There is no nudity and no sexual touching whatsoever," explains Boehm, who was trained in the Hindu principles of tantra and worked as a relationship counsellor when she first moved to the US in 1994, before honing her coaching skills to the more "intimate" area she is now famous for.
"No kissing, either. The skills I want people to learn come before that. Can you sit there with your partner and make eye contact with them without giggling or looking away? It's about generosity of the heart, not wallet. And, most importantly, it's about the ability to provide praise and acknowledgement."
So far, so un-kooky. But what caught everyone's attention in Paltrow's recent interview were the unusual living arrangements - sealed and approved by Boehm - which the actress and her director husband, Brad Falchuk, enjoy.
Despite a five-year relationship and almost year-long marriage, the pair don't live together, choosing instead to spend a maximum of four nights a week with each other at Paltrow's LA home.
Is this all part of the "polarity" Boehm claims is vital in a marriage?
"Listen: all relationships are built on sameness," she says.
"The rapport built when you discover you have things in common, as well as similar values around children, religion, money, exercise ... But the sexual spark that I call 'erotic friction' or 'polarity' follows the exact opposite principle. Because what makes sex 'hot' is the attraction of opposites. Hence we usually have the hottest sex with people we don't even like."
So the less "familiar" we are with one another, the more that polarity can thrive?
"Absolutely. I'm a big advocate of getting as much space as you can," she nods.
"Now, of course, it's a one-percentile privilege to live in separate houses - which a lot of happily married people I work with do - but even if it's just a 'man cave' or a 'she shed', do it."
Smiling, she tells me that her husband of 17 years has his own separate property.
"People should also vacation separately if they can," she adds, conceding, again, that this is not always possible, given financial and familial obligations.
"But regardless of any of that, every couple should consider taking a few of my very easy tips. For one: stop the random touching all the time. No putting out your face for a kiss without even thinking about it, or patting your partner's arm. If you sleep together and eat together and then peck each other on the cheek all the time, your nervous system is going to grow weary of that. And never put sex on a 'to-do list' - even a mental one. Women should never override their body's signals, because that will only lead to resentment."
In her 2018 book, The Wild Woman's Way: Unlock Your Full Potential for Pleasure, Power, and Fulfilment, Boehm talks a lot about the "fairy tale" that has made relationships so much harder for women.
"There used to be only a few things that women had to be good at, but now we essentially have to be a CEO in the boardroom, a stripper in the bedroom, Martha Stewart around the house, supermum with the kids, as well as doing yoga, having a spiritual life, an interesting group of friends and looking good online."
Bringing feminism into a partnership is just another "fairy tale" that belies couples' natural predispositions, she believes.
"I do more than 60 events a year, I am super-busy and consider myself ultra-liberated, but I [still] love domestic things like cooking."
Having a life and friends of your own is crucial, says Boehm. "As is date-night discipline."
I can't hold back a groan. The concept of date nights has always made me shudder, I explain; like trying on an old dress or going back to the same place you holidayed as a new couple, it only tends to prompt unfavourable comparisons. Not to mention the nauseating expression itself.
"Then call it something else. But you have to carve out time for one another. And you should make sure you always meet at the restaurant or movie theatre in order to get some 'friction', having taken the time to get your hair done and maybe fit in a shave of some kind," she chuckles.
"Put the focus on that engagement. And once there, do not talk business, kids or bills. There's nothing sexy about saying: 'Who's picking up little Poppy?' It's the death of hot sex."
On that subject, what does she think of millennials, who have the least amount of sex of any generation in history and are supposedly anti-marriage, too?
"Well, how they'll be able to even sit next to one another without texting is more problematic to me than any relationship beyond that," she sighs.
Boehm needs to go and hop on a plane to New York, where a client awaits. But I almost forget to ask one crucial thing: her rules on technology.
"Oh, that's simple: anytime you want to engage with your partner, you should not have a device on you at all."
My husband always has his phone on the table during supper, I tell her - my voice as shrill and plaintive as the school telltale.
"Tell him Michaela says: 'Take it off'," she glowers, " 'or sex will suffer'. "
