Sensuous is distinguished from sensual by gratifying the senses for the sake of aesthetic pleasures or the delight in beauty of color, sound, or form that is induced while sensual tends to imply the gratification of the senses or the indulgence of the appetites (as of gluttony and lust) as an end in itself.
Sensuous usually means a powerful appeal to the senses or to the esthetic faculties; such as, the sensuous delicacy of a rose petal.
Sensual, on the other hand, refers more to some sexual application; such as, a sensual sculpture of a nude.
The difference between the two words was the original reason for creating the expression sensuous. The poet, John Milton, is said to have invented the word in order to have a synonym for sensual, minus the association with sex. He used the word in an often-quoted formulation of what poetry should be: "simple, sensuous, and passionate".
