This is an interesting question that requires more information before I can fully answer it. That is why it is important to speak with your doctor
. First, HIV (human immunodeficiency virus) is a virus. As such, it requires some source before it can be spread. Whereas some viruses are spread via something as simple as shaking hands or eating food that has been improperly prepared, HIV is most commonly shared via bodily secretions. Unsafe sex is perhaps the most common method, although sharing needles among those who abuse drugs can also be a method through which the virus can be shared or contracted. That is part of the reason that people who work in hospitals take so many precautions to make sure that they avoid contact with bodily secretions. That brings us to your question: if the pen does not have the virus on it, then it should not, in and of itself, be able to spread the virus. If, however, the pen has the virus on it, then it potentially could share the virus. Alternatively, it could scratch the normal mucosal walls of the vagina and make it more possible for a woman to become infected if she were to come into contact with the virus later. Please speak with your doctor about this question.
