Lust, sex desire, is the perverted reflection of this love. The pleasure that one wants to derive out of sex life can be experienced multiplied millions of times by developing one's loving relationship with Krsna. One cannot even imagine what kind of joy one can experience in his heart just by offering his love to Krsna.
Srila Prabhupada, quoted by Bhakti Charu Swami in "Ocean of Mercy" (Bhaktivedanta Book Trust, 2016), p 153.
