Over time, love grows stronger, whereas lust becomes weaker. Psychologist and sex therapist, Shannon Chavez, states that as attachment and bonding grow over time, so does love, but lust is more temporary and fades when sexual desire fades away. If a relationship is based solely on lust, there is inevitably no foundation to fall in love with each other. Lust feels like an exciting rollercoaster, but can only be sustained by physical pleasure. When the real work kicks in, the dynamic either transitions into love, or the relationship begins to fall apart.Psych2Go
