I am 19 years old, and I too have this symptom
... the itchy labia, though mine are the labia minora; and no discharge
, smell, or burning... unless I scratch it. When it first started itching, I was able to resist scratching and I expected it to burn something awful when I urinated, because I suspected a UTI; however, it didn't burn like a UTI, so it wasn't that. It's been itching on and off for three days, so I decided to google it to see if I could find any sort of help.
