recently i was diagnosed with trich....I am dumb founded to how i infected this sti i have never got and sti or std ...me and my partner have only been with each other going on 4years now and he is showing negative on his results when he went to the dr. also says he never cheated on me..so what should i be concerned about.... Is it possible to have had it from a bi-sexual partner i had almost 5 years ago! i was tested 3 months after we were over and every thing was negative... The only reason i wen to get tested is because he had chlamydia!
