I find two things really attractive : passion and innocence.
Nothing is more sexier than passion. The light in a person’s eyes when they talk about their passion is brighter than the brightest star. Their love for what they love to do ignites a fire of attraction.
Nothing is more calm than innocence. The depth in a person’s eyes when they ask an innocent question is deeper than the deepest ocean. Their goodness and kindness towards everyone has a pull stronger than gravitation.
