i had a vaginal discharge that was colored green after i had a sexual intercourse with another man.so,i suspected it was trichomoniasis and i researched about the treatment and i took it named metronidazole for 7 days,but still the kind of discharged remained but is now mild than before without taking the drug..i wonder now why i have this itchiness around my vagina and it has a rashes now.also i had a painful intercourse now with my real partner.and i think i had infected him also.he had now a yellow discharge and he said it sometimes painful to urinate and sometimes not.what should we do?
