Gyn exam: Get checked and abstain from any touching, foreplay r intercourse until examinated. Avoid tight clothing or wiping. Abstain if you have been sexually active, .

See doc: Could be infection or irritation from something in your environment, i.e. new soap , detergent, pads. Need to be examined.

See a doctor: The symptoms suggest an infection or an irritation. You may initially try applying an OTC anti-fungal cream topically. If that does not help, then I would recommend that you get it checked out by a doctor.
