i started having vaginal itches about four days aftersexual intercourse with my present boyfriend.i dont think it's STD because we used a condom the first time but during the process he had used his fingers. upon fours i started having intense and rapid onset of vaginal itching followed by yellow watery discharges. i went to the doctor and recieved Klion and Sporasec. it stopped for a few weeks then continued again. i'm worried because i feel so uncomfortable.
