"Lord Kṛṣṇa’s name is Madana-mohana, for He can subdue the god Cupid, or lust. Only by engaging in the service of Madana-mohana can one curb the dictates of Madana, Cupid. Otherwise, attempts to control the senses will fail."

"If you increase your attraction for Kṛṣṇa, then naturally you lose attraction for sex. That is Kṛṣṇa consciousness. Therefore Kṛṣṇa's name is Madana-mohana. Madana means sex life. He can enchant even madana."

Bhagavad-gītā 7.1

Nairobi, October 27, 1975

"But Kṛṣṇa is the only means. When one is attracted by Kṛṣṇa, Madana-mohana... Madana means lusty desires. And Kṛṣṇa, Madana-mohana. He is so attractive that one forgets lusty desires. Therefore His name is Madana-mohana. So if you don't contact with Madana-mohana, then you'll be suffering madana-dahana. Dahana means this, dahyamānānām, always suffering the blazing fire of lusty desires. Unless you become Kṛṣṇa conscious, you'll have to suffer."

Śrīmad-Bhāgavatam 1.7.22

Vṛndāvana, September 18, 1976

"Their only happiness: yan maithunādi, sexual intercourse, that's all. Yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham. Very insignificant, very abominable combination of man and woman. And they are working so hard day and night. That is the only pleasure. So vairāgya means when you will be detestful to this sex pleasure. That is called vairāgya. "No more." Yad-avadhi mama cetaḥ kṛṣṇa-padāravinde. That is possible only when you are perfectly Kṛṣṇa conscious. Otherwise it is not possible.
Therefore Kṛṣṇa's name is Madana-mohana, and the material is madana-dahana. In the material world everyone is suffering by the piercing arrow of Cupid, man or woman. The Madana, Cupid, is piercing the arrow to man and woman, and the woman is mad after man, and man is mad after woman. But when you see Kṛṣṇa actually, then you see Madana-mohana. Then there will be no more suffering of the piercing arrow of the Cupid. That is called akuto-bhayam, no more fear. No more fear. Now you become fearless."
