It's actually a really good idea to bring a friend with you if you're working with a photographer for the first time that you haven't met before. It's actually kinda hinky if they refuse to let you bring someone along. Stay safe!
You know what's weird? I ended up doing a photoshoot last week. I scripted this comic in June or something, and now I've got all this extra inspiration for the storyline. My experiences are a bit different than Jackie's, though. She tends to take things way more seriously than I do. If you feel like checking out what I did, you can look at them here on my burlesque blog. Many of them are nsfw, be warned.
