I'd like to take a golden shower!
Are you sure that you mean golden shower?
It seems like something that would be good for my usual hygiene issues.
Well, if the other person or people consent then there shouldn't be any issues with that. It is completely fine to fantasize and want something like taking a golden shower, as long as you don't walk around telling everyone about the kink that you're into at the moment because most people won't want to hear about this.
I'm very open about my sexual kinks and have nothing to hide.
I think that you should look up what a golden shower is first. There is nothing wrong with having fantasies, just make sure that you know what you are getting into first.
