Attractiveness or attraction is a quality that causes an interest, desire in, or gravitation to something or someone.[1]:59[2][Notes 1][Notes 2] Attraction may also refer to the object of the attraction itself, as in tourist attraction.
Physical attractiveness is the perception of the physical traits of an individual human person as pleasing or beautiful. It can include various implications, such as sexual attractiveness, cuteness, similarity and physique.[citation needed]
Physical attractiveness can also include the attraction of smell. Pheromones secreted by animals and humans alike can attract others, and this is viewed as being attracted to smell.[3] Human sex pheromones may play a role in human attraction, although it is unclear how well humans can actually pick up on the pheromones of another. source:wikipedia
