I do not think I understand your question. It is kind of like asking can you catch a cold from your self. If you are HIV positive, how can you catch it again if you already have it.
If you are asking if sperm from an HIV positive person came in contact with a cut on another person, would that person catch HIV I would have to say that is highly likely. HIV is spread by body fluids. Sperm is a body fluid.
If you are asking if you can get HIV from your own self by playing with yourself, spanking the monkey and getting sperm into a cut and you do NOT have HIV, then the answer to this question is NO.
