Coprophilia is a sexual fetish people feel when they come into contact with feces. Coprophilia can be 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.
A coprophagophobe is someone who has a fear of consuming feces. But the word isn't found anywhere.
