Problem down there! help?

Its ichy! it all started a few days ago when i went to the beach and slept in my bathing suit bottoms after being in salt water. its on the inside of my vagina and clitoris. The ich is not unbarrable, its not that bad most of the time, and it kinda comes and goes. its not an STD or anything cause i havnt had sex and its not a yeast infection i dont think cause the discharge is normal, have any idea what its from and how to fix it? i dont want to go to the gyno, so im hoping i can cure it somehow without medicine, im hoping its just an irritation of some sort,, im pretty sure its not an infection, its not swolen or red or anything, just a little ichy. cold water seems to sooth it. will drinking things with lots of antioxidents help?
