What are the reasons for vaginal irritation and burning sensation?

Hello doctor,

To begin with, I would like to say that I have never had sex or kissed anyone before. I recently did a urine test and the result was negative. My urine used to burn because I was douching accidentally. However, I started washing my vagina more cautiously and the symptoms resolved after a day or so. However, even now it slightly burns but not as badly as before. Could this be due to dehydration or intake of soda or friction?

My vagina feels weird sometimes, and I could feel irritation rather than a burning sensation. Can this occur due to my Fordyce spots getting inflamed from friction due to my clothing? My discharge is normal and its consistency ranges from liquid to relatively thick but is always white and odorless. I am slightly confused with the results and the symptoms. Is this a recurring yeast infection?

This has been coming and going for a year now but, as I said, it stopped recently. But, these spots persist. They do not hurt to touch. Are these spots Fordyce spots or are they herpes lesions? Weeks before I got my urine tested, I got a red spot on the inside of my nose. Later, there was pus formation and it burst. The pus was thick and it bled a little, and it hurt to touch. There was scab formation. The spot went off in about four to five days. I do not pick my nose but I kind of pull on the sides because it feels irritating at times. I did not care much about this until I started picking my nose frequently. Could this be a cold sore or pustules? Kindly help.
