The original Kamasutra was written by Vatsyayana Mallanaga in the 2nd century CE. It is not just a sex manual but also explores the philosophy of love, emotional fulfillment, and the relations between men and women.
Keep in mind that while the Kamasutra is an important piece of literature, some versions might contain explicit content, so viewer discretion is advised.
