Constantly wet panties. It smells of urine. No discharge that I see. Not itching or burning. What is happening? Had Chlaymdia and treated it. Is it Bv

Vaginal discharge. If it were urine, you probably would know -- for example, if you lose a bit of urine when straining, coughing or sneezing. Otherwise it's probably vaginal discharge. Odor is very subjective -- but noticealbe vaginal odor often is due to bacterial vaginaosis, as you apparently suspect. BV can accompany or follow chlamydia. See your doctor for diagnosis and treatment. No sex in the meantime.
