If her labias smell, it's a matter of poor hygiene. If her vagina smells, it may be a matter of poor hygiene, or bad diet/infection/etc. The mucus in the vaginal canal does have a scent/flavour, but it's normally quite tolerable, and sometimes rather tasty, and thus fully acceptable to wind up getting some on your tongue. Compare to the flavour of precum/cum: it's quite tolerable/not at all bad normally, unless the person smokes/has a shoddy diet (fastfoods, etc)/other problems.
