Itchy white spots that are on the skin can be many things but if you and your girlfriend recently developed them and neither of you had them before then they could be a type of infection. A possibility is Molluscum Contagiosum. These are usually small and have a very small umbilication in the center (a slight depression). If that is what you have, they respond best to removal with a small instrument called a currette. You will have to see an ophthalmologist or dermatologist to verify what these are.
