How is my vagina cleaning itself if my vagina doesnt have any discharge. my vagina isnt dry and i do produce discharge when aroused. ive also been noticing a frito smell lately when my legs are open, cant tell if its a yeast infection or normal?

If no itching or irritation, probably no yeast infection; and yeast usually causes little or no odor. The scant moisture you describe sounds entirely and a healthy vagina. What gave you the idea that you must have ongoing obvious discharge for a normal vagina with natural cleansing? Almost certainly all is well, but if you remain concerned see a gynecologist for a reassuring examination.
