Srimad-Bhagavatam: Canto 9 - Chapter 1 - Verse 20
Sanskrit:
उर्वश्युवाचकस्यास्त्वयि न सज्जेत मनो दृष्टिश्च सुन्दर ।यदङ्गान्तरमासाद्य च्यवते ह रिरंसया ॥ २० ॥
ITRANS:
urvaśy uvācakasyās tvayi na sajjetamano dṛṣṭiś ca sundarayad-aṅgāntaram āsādyacyavate ha riraṁsayā
Translation:
Urvaśī replied: O most handsome man, who is the woman whose mind and sight would not be attracted by you? If a woman takes shelter of your chest, she cannot refuse to enjoy with you in a sexual relationship.
Purport:
When a beautiful man and a beautiful woman unite together and embrace one another, how within these three worlds can they check their sexual relationship? Therefore Śrīmad-Bhāgavatam (7.9.45) says, yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham.
