Black hair, brief nudity . . . sounds like Mr. Skin’s kind of girl. Monique Curnen may be familiar to viewers of the cable series Dexter, but that’s only half the story. The other half is Half Nelson (2006), an arthouse drama that is also Monique’s first and only flash onscreen. About an hour into the film Ryan Gosling is goosing Monique’s naked sacks. Half nelson, but fully erect!
