Personally I really like whores and begrudgingly consensual "tribute" stuff with royalty. It can be a lot of things. I really love the Zentara series that someone linked into the OP for instance. Seeing other people's writing could be informative.
I've got no idea where you discuss writing smut. I feel like maybe I saw a general on some board at some point...
Smut advice is probably pretty general. You could apply just general smut advice into specific fetishes.
