rent a video for whichever niche and listen to the language being used and get a feel for the overall attitude, or see what toys and models are common and how they're presented, even see what the customers are like
I think that the only language you will get out of a porn video is a bit of moaning and groaning and of course some really cheesy music. But of course, it does make a great excuse to go hire a porn video (no really, honey, its research )
