Coprophilia
Coprophilia is a sexual fetish people have where they enjoy coming into contact with feces. Possible other names for coprophilia include scat-play, scat kink, or shit kink. Coprophilia is said to be liking the smell, taste, or feel of feces in a sexual way. The feeling can be either through touching the skin or through rubbing the penis head against feces. Enjoyment can also be made from the feeling of feces passing through the anus, or having a sexual partner excrete feces onto their chest.
