It could be early symptoms of contact dermatitis. Have you used a new underwear or soap? If yes, it is the culprit. You can buy the lidocain 4% ointment or cream (OTC) at drug stores like CVS. You can use the cream on the itching part when figuring what you are allergic to.

Contact dermatitis is one possibility, but it could also be a yeast or fungus infection, or one of several less common possibilities. Suggest seeing your gynecologist or a dermatologist for proper examination and treatment.
