For myself, I do a lot of innuendo, rather than blatant comments when in a room. But, then again, I tend to try and keep it lighthearted in general if I'm in a model's room. Of course, it depends upon the room, model, etc. I think it can be done right in a setting where it might not be the norm. Sometimes, leading up to it. One model I know does a great job of balancing conversation and dirty talk. But, she's hardly ever on anymore.
