The sensual desire you’re feeling has drawbacks that far outweigh the gratification, and you’d be much better off focusing on the breath to let the mind gain a sense of inner peace and calm instead.

"If you’re honest with yourself, you’ll be able to find some way for realizing that the sensual desire you’re feeling has drawbacks that far outweigh the gratification, and that you’d be much better off focusing on the breath to let the mind gain a sense of inner peace and calm instead."

~ Thanissaro Bhikkhu "The Karma of Mindfulness: The Buddha's Teachings on Sati and Kamma"
