I also like an element of realism in my stories. Fresno is an obvious real location, with real stores, restaurants, streets, etc. Luigi's is totally made up, a combination of various Italian restaurants I've been to over the years. Trelio's is a real Fresno, high end restaurant, but what happens there is a total fabrication. So is Studio 65 dance studio, which specializes in Latin dancing, but what it looks like and who works there are fabrications. Don't go asking to dance with Ricardo. He's made up. All the people are made up.
The streets I named in Fresno when the gang is tailing Alice's husband are real streets, as are the apartments they found him at, but the rest is malarkey. The Pacific Crest trail is a real trail, but I have no clue if you'd ever see a body of water where Scott, Julia and Lisa rest and play with Sarah. I'm thinking Scott and Julia reside on the East side of Fresno, near Clovis, closer to Yosemite, but it's an imaginary street in a nice neighborhood. The sex toys I talk about are real with the exception of the Slave Trainer. I've used a few, but not nearly all of them, and I don't know how well they all work. If you do some web searches, you sometimes see what appear to be some of the toys described being used by others. I've seen a video by a group called Videodrome on MeWe which appears to be using a Silhouette or Impulse or similar, which is amazing. It's where I conceived of the Impulse scene with Becky.
