I had unprotected vaginal sex ( I am a female) with a guy for about 1 to 2 minutes. He did not climax and I do not have any venerial diseases (open wounds, etc). Assuming that he had HIV (God I hope not, but just assuming he did), what are my chances of contracting it from him from this one experience? Also, when is the earliest that I can go and get an HIV test (mouth swab) and be absolutely sure that the HIV will show up?
