Kama is the Enjoyment of the Five Senses of Hearing, Feeling, Seeing, Tasting and Smelling

Kama is the enjoyment of appropriate objects by the five senses of hearing, feeling, seeing, tasting and smelling, assisted by the mind together with the soul. The ingredient in this is a peculiar contact between the organ of sense and its object, and the consciousness of pleasure which arises from that contact is called Kama.

M. Vatsyayana, Kama Sutra
