Your risk was virtually zero.
Otherwise, I am not going to answer. Apparently you missed the following paragraph, which is prominently displayed after to click the "Post a Question" link. I'm only responding now because this is the first day of the new policy, and this reply helps me emphasize it to other forum users:
"If you have not done so, please review other threads in our archives and the FAQs for questions similar to yours and Dr. Handsfield's replies. Questions that duplicate other frequent ones, for which abundant replies exist, and that have little educational value for other forum users, will be DELETED WITHOUT RESPONSE. YOUR DONATION WILL NOT BE REFUNDED. The most common examples of such questions are those about low risk exposures to HIV, such as oral sex, hand-to-genital exposure, and nonsexual contact with possibly infected blood or body fluids."
Good luck-- HHH, MD
