It was only once and each person did one line. As it was out of my character, I of course looked up the
health risks the next day and was surprised that you may be able to catch HIV this way. I looked through some of the older posts (not many to the docs) and did not see any past 2009. It seemed the doctors really were unsure, sometimes they would recommend testing, other times they would say zero risk and no need for testing which confused me.
