) I think I would only be concerned if something changed a lot, such as a really, really strong
odor.
Mild odor can just be because of the interaction of sweat or urine and the natural secretions once they are out of the body. Don't go poking things up there on a regular basis, you might add bacteria, but if you are worried about a smell on a particular occasion, AFTER A BATH when the area is really clean, you could put a Q-tip into your vagina and swish it around, then smell it.
