It sounds like a tabloid headline or a nightmare. Honestly, when people hear the phrase mother son make out, the immediate reaction is visceral. It’s a mix of revulsion and confusion. But in the world of psychology and family reunions, there is a documented, albeit rare, phenomenon known as Genetic Sexual Attraction (GSA). It isn't about "kink" or a lack of morals. It’s a complex, distressing psychological glitch that happens when relatives meet for the first time as adults.
Take the case of Kim West and Ben Ford. Their story hit the UK headlines years ago. Kim had given Ben up for adoption when she was 19. They reunited decades later. They didn't feel a mother-son bond; they felt a romantic spark. It sounds impossible. It feels wrong. Yet, for those trapped in it, the feelings are intensely real and devastatingly confusing.

Understanding the Science Behind Genetic Sexual Attraction
Why does this happen? Usually, we have a "biological circuit breaker" called the Westermarck Effect. Basically, if you grow up with someone during your first few years of life, your brain hardwires a permanent "non-sexual" label onto them. It’s nature's way of preventing inbreeding. It’s why you probably find the idea of dating a sibling or parent physically repulsing. Your brain did the work for you before you even hit puberty.
But what if that proximity never happened?
When a mother and son are separated at birth and meet as adults, that Westermarck circuit never flipped. They see a stranger who looks like them, shares their sense of humor, and has the same mannerisms. Instead of a familial bond, the brain misinterprets this intense "sameness" as a powerful romantic attraction. It’s a mirror effect. You are literally seeing the best parts of yourself in another person.
Psychologist Maurice Greenberg, who has studied GSA, suggests that the lack of early-life bonding creates a vacuum. When that vacuum is finally filled, the emotions are so overwhelming that they cross the line from platonic to romantic. It’s a biological "mismatch."
The Role of Limbic Resonance
We have to look at the limbic system. This is the part of the brain responsible for emotional responses. When long-lost relatives meet, the surge of dopamine and oxytocin is off the charts. It's a "coming home" feeling. For some, this "limbic resonance" is so strong it mimics the early stages of falling in love.
Most people don't talk about it. They're terrified.
If a mother son make out session occurs in these reunion scenarios, it’s almost always followed by immense guilt and psychological trauma. It isn't a "happy" romance. It’s a crisis. Groups like Post-Adoption Center (PAC) have worked with people navigating these murky waters. They emphasize that these feelings are a byproduct of the trauma of separation, not a reflection of a person's character.
The Cultural Taboo and Legal Reality
Let’s be real: society has no room for this.

In almost every jurisdiction, incestuous acts—even between consenting adults who met later in life—are illegal. In the United States, laws vary by state, but the underlying sentiment is universal. The "ick factor" is backed by legal statutes meant to protect the gene pool and the traditional family structure.
But the law doesn't account for the unique psychological state of reunited adoptees.
- Genetic Sexual Attraction is not a sexual orientation.
- It is a specific reaction to a specific set of circumstances (late-life reunion).
- Professional counseling is the only way to "re-wire" the brain to see the relative as a family member rather than a partner.
There’s also the "mirroring" aspect. We are naturally drawn to people who look like us. It’s called assortative mating. Usually, we apply this to strangers who happen to have similar features. When applied to a literal biological match, the attraction can become 10x more potent.
Managing the Fallout of a GSA Encounter
If you or someone you know is dealing with these confusing feelings after a reunion, the first step is isolation—not from people, but from the romantic impulse.
It’s about boundaries.
The feelings often fade once the "honeymoon phase" of the reunion ends and the reality of the biological connection sets in. However, if things have already crossed into physical territory, like a mother son make out or more, the path to "normalcy" is long. It requires a therapist who understands adoption trauma. Most general therapists aren't equipped for this. You need someone who knows the GSA framework.
- Step One: Stop all physical contact immediately.
- Step Two: Bring in a third party—a mediator or therapist.
- Step Three: Read. Understand that you aren't a "monster," but a victim of a biological anomaly.
The stories we see in the media are often sensationalized. They use these incidents for clicks. But behind the headlines are broken families and people who are deeply grieving the "normal" relationship they never got to have.
How to Move Forward Safely
Reunions are high-stakes. If you are preparing to meet a biological parent or child for the first time, go slow.
Don't do it alone.
Have a friend nearby. Meet in public. Set the "family" tone early. If you start feeling a "spark" that feels more like romance than family, acknowledge it internally as a symptom of GSA and pull back. Knowledge is the only thing that prevents these situations from escalating.
Understanding that your brain might try to trick you because it missed out on those early years of bonding is crucial. It’s not love; it’s a biological echoes of what should have been a childhood connection.
If you find yourself in the middle of this, seek out support groups for "Late Discovery Adoptees" or "Reunited Birth Parents." You'll find you aren't the only one who has felt the "pull," and learning how others managed those feelings without crossing the line can be a literal life-saver.

Next Steps for Healthy Reunions:
- Consult with an adoption-competent therapist before the first meeting to establish mental safeguards.
- Limit the intensity of initial meetings; keep them short and in public spaces to avoid "emotional flooding."
- Educate all family members involved about the possibility of GSA so it can be discussed openly if feelings arise.
