Is it normal i keep thinking about this woman who eats dog poop

Hi. OK. So there is this woman that likes to eat dog poop, she likes the smell and taste of it, no matter how gross that may sound, for some reason I feel sexually aroused by this. I have no idea of why because I hate poop. I don't think I'll kiss her or smell her breath once she has just eaten poop. I just can't stop thinking about her.
