I can not find title of this movie, and I only found this dialog on web.
We see a clip of one of Ron's early films in which he's screwing a girl on some stairs:
Ron: Can you, can you do something for me?
Girl: What?
Ron: I mean, er, can you do something my wife never does?
Girl: What?
Ron: Can you talk dirty to me? Dirty? Come on, come on.
Girl: Oh brother.
Ron: Talk about your assehole?
Girl: Why? You're in my cu_t.
I am sorry to write it like this, because I don`t have any other data or source.
Thanks anyway.
