Classical Mahayana scholars like Shantideva and Aśvaghoṣa considered non-vagina sex to be sexual misconduct. Shantideva based his views on quotes from the Saddharma-smrtyupasthana Sutra. According to Mizuno Kōgen's study, Saddharma-smrtyupasthana Sutra is related to Ghoṣa's Abhidharmāmṛtarasaśāstra, and is compiled by Sarvastivada (possibly from someone related to Ghoṣa after the 2nd century). In the Great Treatise on the Perfection of Wisdom (Sanskrit: Mahā-prajñāpāramitā-śāstra), the Madhyamaka scholar Nagarjuna mentioned the non-vagina sex restriction as based on coerced action toward one's own spouse. Mentioned in Saddharma­smṛtyupasthāna, the man who have sex with man will enter the hell of Copious Degeneration. Even if the sentient being is reborn as human after suffering in the hell, all spouses of the sentient being will stray.
