There are popular statements found in smṛtis and nīti sāśtra that women have eight times more kāma than men. For example:
kāmaśca aṣṭā-guṇaḥ smṛtaḥ
(Garuḍa-purāṇa 1.109.33, Hitopadeśa 2.71)
The word kāma in these statements is often thought of as sexual "lust," giving the impression that śāstra considers women to be eight times more sexually lusty than men.
