Suggest Treatment For Clear Discharge And Foul Smell From Vagina

hello, I am 18 year old female i weigh about 255 lbs. I"m not sure what else you want to know. I know this is kind of embarrassing but i don't know what else to do. I seem to have a very strong foul odor coming from my vagina. I shower daily, i use feminine sensitive wash, i change my panties, and i even use feminine towels during the day when the smell is unbearable. The smell is very strong, but i'm not sure what to compare it to for you. I also have discharge. It is either clear or white but i feel i get alot of discharge, enough to make my panties very wet. I have already gotten tested for STD's and all that stuff. I'm not in pain or itching or burning or anything. I mostly just feel uncomfortable from the wetness and the odor. Please help me
