I have, occasionally, when surfing, run into sites that feature brown showers or golden showers, or other stuff like that. I find such things to be disgusting and not at all exciting but there are some who get off on it. I wouldn't call such things the worst ever because that is just my opinion. Some people might consider it to be great. I like to see or read about anal sex but there are those who find that disgusting. They might say an anal story is the worst while I think it is one of the best.
