By engaging the mind in Krsna, it is possible. The more you advance in Krsna consciousness, you’ll lose interest in this sex life. In Vaikuntha there is no sex life because the sex pleasure is not the foremost pleasure in the Vaikunthaloka. The sex pleasure is foremost here in this material world. They have got so much transcendental spiritual pleasure, this sex pleasure — they are astonished: is that pleasure? Phu! [makes spitting sound] Yad-avadhi mama cetah krsna-padaravinde nava-nava-rasa-dhama… [Yamunacarya].
