I never wrote an erotic story until today. It's a true story and I'm not sure what category to file it under. It's about an experience I had with my doctor (a woman) giving me a prostate massage. I'm thinking maybe or Fetish? What do you think?
Going by what you've mentioned it sounds like your story would be fine in the masturbation category with additional tags that relate to "doctor", "prostate" etc so the reader has an idea what to expect. If a moderator thinks it's more suitable for another category they're able to change it for you before approving your story.
