I am not ashamed of my fetishes mainly because I keep any that are the most disturbing (most likely straight shota and incest) in the realms of fiction. I don't indulge in my sick fantasies IRL, so I feel that it is no harm to anyone and only releasing my sexual tensions. Now with some lesser fetishes such as having a girl/man dress as a cow/bull or some spanking, I enjoy experiencing with an actual person with the same fetish. I guess it would really depend on the fetishes someone desires. But there is nothing wrong with feeling ashamed with a fetish, in my opinion, because it is a deterrent from doing something IRL that is a crime or could be morally wrong. Human nature, to me, is fucked in the first place, and is willing to do many things for some sort of pleasure. Its mainly social and moral standards that would equate to feeling ashamed. Having a place like this helps eliminate the things you are ashamed with from your consciousness. So maybe feeling ashamed isn't necessary, but just your mind telling you that it is greatly looked down upon in society, and how that won't assist you from a level of approval from your peers. But that is just my small, silly take on the subject.
