Virginity has nothing to do with vaginal odor. It is normal for any woman, virgin or not, to have a certain amount of odor down there because there isn't much air circulation through our clothing. We're human. We sweat. We smell. Women smell and so do men and their man-parts.
You can try wearing loose clothing, like skirts, and cotton underwear. Fabrics like nylon hold moisture, which allows bacteria to flourish, which then causes odor. We women produce a certain amount of clear vaginal discharge during our reproductive years. It can be lighter or heavier from day to day depending on where you are in your menstrual cycle. As long as the discharge is clear, it is completely normal. This discharge is the same lubrication your body will produce even more of when you are sexually stimulated. That lubrication is important during sex. Without it, sex can be painful and certainly not pleasurable for either you or your partner.
If this odor you notice is something new and out of the ordinary, then go see a gynecologist. Women can get vaginal and urinary tract infections for all kinds of reasons other than having sex. Matter of fact, it wouldn't hurt to see your gynecologist for a checkup and perhaps some reassurance that you're completely normal. :-)
