Menopause and Desire: A Modern Understanding
Menopause may change the body, but it does not kill desire. What often declines is sex drive—the physiological urge—not the deeper psychological experience of desire.

When these conditions are present, desire does not disappear—it becomes accessible in new, more intentional ways. Dr. Aleida…

Infidelity in the Digital Age: Why Good People Cross Lines
Infidelity in the digital age rarely begins with the intention to betray. More often, it starts with a conversation that feels alive, a connection that feels effortless, or a sense of being seen again. Online spaces amplify opportunity, speed, and emotional intensity, allowing desire to awaken without reflection or relational containment. When erotic expression has…

The Missing Space Between Love & Sex: Introducing the Concept of Erotic Intimacy
Most couples believe intimacy has only two forms: the emotional closeness that feels safe, and the sexual connection that feels physical. But in my clinical work, I see something else — a missing space between the two, a space where desire actually lives. I call it Erotic Intimacy: the mental and emotional field where curiosity,…

When Desire Turns Elsewhere: The Psychology of Infidelity
Infidelity rarely begins with the intention to betray. In clinical practice, it most often emerges when desire has no place to be expressed within the relationship.

Desire, Drive, and Arousal: Understanding the Three Systems That Shape Our Erotic Life
We often use the word desire to describe experiences that belong to three different systems: sexual drive, arousal, and true erotic desire or libido. And when these are confused, people begin to believe they are “broken.” They’re not. Drive is a biological impulse. Arousal is the body’s reaction. But desire is something entirely different— it…

The Enemies of Desire: Why We Stop Wanting
Most couples don’t lose desire — they lose access to it. Stress, emotional exhaustion, resentment, and over-familiarity don’t destroy desire; they simply cover it. When we understand these hidden forces, we stop blaming ourselves or our partners and begin to reclaim the space where desire can breathe again. Dr. Aleida Heinz

The 7 Erotic Languages: How We Learn to Speak Desire
Desire doesn’t disappear — it becomes inaccessible when partners stop speaking each other’s erotic language. The 7 Erotic Languages reveal how each person experiences desire through their senses, imagination, and self-perception. When we learn to understand these internal languages, desire becomes clearer, intimacy deepens, and relationships rediscover the aliveness they thought they had lost. Dr.…

Por qué el Amor no es Suficiente en las Relaciones de Largo Plazo
En las relaciones de largo plazo, el amor suele mantenerse… pero el deseo se vuelve silencioso. No porque algo esté roto, sino porque el amor y el deseo operan con lógicas psicológicas distintas. Comprender esa diferencia transforma por completo la manera en que nos relacionamos. Dra. Aleida Heinz

Why Love Isn’t Enough in Long-Term Relationships
After more than two decades working with individuals and couples, I’ve learned that desire doesn’t disappear—it becomes inaccessible. Love offers safety, closeness, and stability, while desire needs imagination, space, and aliveness. When we confuse the quieting of desire with a lack of love, we misread our relationships, our partners, and ourselves. Understanding the psychology of…
