My private is always getting this stringy discharge in my panties it be clear or yellowish some times and fishy smell but no std what is it bv?

BV: This sounds very compatible with bacterial vaginosis but the best means of making certain of what this is would be to let a physician examine you and the discharge and then to diagnose and treat appropriately.

Cervicitis: Your complaints indicate mostly cervovaginitis BV,trichomona, or nonspecific infection and visit to Gyn by office micorscopic exam will confirm dx or to send discharge for lab culture. Local hygiene is important at all time and proper diet and be healthy will be important to minimize commom infection. good luck
