Dominicans aren't hands on pimps. They might be sitting on a motochoncho or passing out change, but they are watching everything. It's not like America where the pimps wear the fancy outfits and drive outlandish cars.
Any gringo that doesn't speak Spanish and says if he lived there pussy would be free is talking crazy.
Now Cuba pimps in Cuba are another story. They will actually follow you and the girl and make their presence known. Completely rude dudes.
