I have a question about std's I know of the common ways of getting it, however is it possible getting one from swapping fluids, what I am really trying to get at is that I am in working relationship between two women, Female 1 and I have already have been checked and we have been cleared, female 2 has never had sexual contact before so she is still a virgin. Regardless of that she still decided to check anyways and was cleared. Is there any possible way of getting a STD or contracting something else?
