There's not much that can be added here aside from character viewpoints at this point. So, I will start by saying that sexual RP is somewhat important in Vaughn's character. He was born an enslaved whore. He knows things. He is nearly an entirely different character when it comes to sexuality because he's confident in his knowledge. This is largely why he's so nervous when given other tasks* (like talking normally to people). He doesn't have the confidence as he was told since he was a child that his only worth is that of pleasing others in a sexual manner. Normal conversations about normal everyday things still confuse him. Of course, over the past year he's been free, he's learned much so it's easier to talk about normal things.
*Well, that and his drug abuse, but that's a different topic altogether.
