As the result of purity, there arises indifference toward the body and disgust for physical intercourse with others.

When cleanliness is developed it reveals what needs to be constantly maintained and what is eternally clean. What decays is the external. What does not is deep within us.
Source: English translation of the Yoga Sutras of Patanjali (Swami Jnaneshvara Bharati)
Through cleanliness and purity of body and mind (shaucha), one develops an attitude of distancing, or disinterest towards one's own body, and becomes disinclined towards contacting the bodies of others.
