Love of romance. Butterflies, attraction, and affection.
Those who identify with Eros are excited by the romantic aspect of relationships. They're often the type to believe in love at first sight, as the initial attraction they feel for someone is immediate and intense.
These types thrive on physical affection and feel passionately about their partner. When they fall in love, they fall hard, and try to keep the flame alive for as long as possible. Because of this, Eros lovers tend to feel the need to deepen the relationship and take it to the next level (both emotionally and physically) fairly quickly.
Eros love in its purest sense is driven by a motivation for enchantment and fantasy. There is, within that, a desire to understand and be understood. To find someone to be fully naked with in every sense of the word. It is the love of cupid, blindfolded to reason and logic.
