Thanks for posting your query.
You should not be worried about the problem you posted. This is because according to researches and studies- by minor custs,crusts and sores the risk of HIV
infection is negligible. In your case it is even better condition as you do not know the status of the female- HIV positive or negative. Even if we consider her to be positive it Don't mean high risk of infection. As for your knowledge we medical personnel are working day and night we so much of blood and body fluids and we do have minor abrasions and cuts (You probably are not reading in anywhere that HIV has increased in medical /paramedical field!!). So you should not be worried about. But you should take care next time.
all the best.
