I went to the dr last week because i thought i had a yeast infection...turns out i have trichomoniasis .... my bf and i have been together 6 months... we work together and live together... i inow he hasnt cheated and neither have i...he was tested today and his test came back negative...how is that possible? I know my ex husband cheated on me..he could have possibly given it to me...but why wouldnt my bf have it? I am really confused..
