an.10.237 Aṅguttara Nikāya (Numbered Discourses)

“Bhikkhus, for direct knowledge of lust, ten things are to be developed. What ten? The perception of unattractiveness, the perception of death, the perception of the repulsiveness of food, the perception of non-delight in the entire world, the perception of impermanence, the perception of suffering in the impermanent, the perception of non-self in what is suffering, the perception of abandoning, the perception of dispassion, and the perception of cessation. For direct knowledge of lust, these ten things are to be developed.”
