What do you think about this extremely strange fetish that I have?
Really? I'd need to know more about it first to answer that question.
I am interested in swallowing feces.
Its ok for people to have different types of fetishes. People have the freedom to express their sexuality in any way they please. While the fetish may be very unique, this is simply someone's preference.
I can understand people being disgusted by this.
Yes, there will be a lot of people who find that disgusting, but it is your own private fetish and there is nothing wrong with that. As long as you practice safety and clean up after yourself, others should show you respect for your sexual life.
