Understanding Sexual Desire
Many clients come to me grappling with dilemmas of desire—whether they feel too much, too little, or somewhere in the middle. Fortunately, we can turn to SCIENCE to help us better understand and navigate these challenges.
The Fire Triangle, a concept from chemistry, can help us break down the core elements of desire and intimacy. Just as a fire needs three essential components—heat, fuel, and oxygen—to burn, so too does sexual desire. Let’s explore how each of these elements contributes to sustaining passion and connection in relationships.
1) Heat: The Spark of Attraction
“Without sufficient heat, a fire cannot begin and it cannot continue.”
This may seem like an obvious first step, but it’s fundamental: without a spark, there is no fire. In relationships, that initial attraction—whether physical, emotional, or intellectual—serves as the activating energy that propels the connection forward.
Sometimes, however, this primal need for heat gets rationalized or downplayed. You may hear individuals say of their partner, “They’re my best friend,” “They’re the nicest person,” or “They’re reliable.” But if the sexual connection is absent or minimal, the fire just won’t burn.
Heat must reach a critical threshold—often called the "flash point"—before a fire can sustain itself. In romantic relationships, especially long-term ones, this is key.
While intense attraction at first sight may not always be necessary, a certain level of chemistry must build early on to ensure the relationship can thrive through boredom, aging, and other life changes.
2) Fuel: Sustaining the Flame
"WITHOUT FUEL, A FIRE WILL STOP."
Just like a fire needs a constant supply of fuel, desire also requires ongoing nourishment to remain strong. The types of fuel can vary, and just as different materials can burn at different rates, so too can love be nurtured in unique ways.
Gary Chapman’s Five Love Languages offer a useful framework for understanding how people fuel their relationships. The five love languages are:
Physical Touch: Holding hands, kissing, sexual intimacy
Words of Affirmation: Compliments, verbal praise, “I love you”
Acts of Service: Cooking, running errands, fixing things
Gift Giving: Thoughtful presents, whether big or small
Quality Time: Uninterrupted time together, free from distractions
Each person tends to have a primary and secondary love language. By recognizing and speaking your partner’s love language, you provide the right fuel to keep the relationship burning brightly.

3) Oxygen: The Space to Breathe
"..too often, as couples settle into the comforts of love, they cease to fan the flame of desire. They forget that fire needs air.”---Esther Perel, Mating in Captivity
Desire requires some element of space and distance for individual dreams, interests, and passions to exist and thrive, along with those that are shared. I often stress to clients the importance of balancing the "me" with the "we." The Brangelinas and Bennifers usually implode, explode, or wither away, making horrible movies in the process.
Esther Perel, a brilliant sex therapist with a seductive accent, has an excellent TED Talk on how to let your relationship breathe and deepen your intimacy in the process.
Bring it All Together: The Alchemy of Desire
When heat, fuel, and oxygen come together in the right balance, you create the ideal conditions for an enduring and passionate connection. Understanding these elements and applying them in your own relationship can reignite the flames of desire, even in the context of long-term commitment.
