“Sensual” usually relates to physical desires and experiences, and often
means “sexy.” But “sensuous” is more often used for esthetic pleasures,

seats in your new car may be sensuous; but if they turn you on, they
might be sensual. “Sensual” often has a slightly racy or even judgmental
tone lacking in “sensuous.”
