Brian Fog hit me, the star trek reference was another post on another thread here, one very delicate one about women
being the means of transmission of virus. WTF?? The person posting was genuinely concerned, not so much about the having-sex-with-a-woman who had sex with another person earlier who had Hep C, or B maybe, it was confusing. He was, and rightly so, afraid he may have brought something more out of the relationship than a smile.
