go to a spanish store and get something called lemisol...its like summers eve except it make you feel like a peppermint is there..and use hydrocortizon ointment..it harder to rinse off when you pee..not cream that will irratate it and if you buy new underwear wash them before you wear them..and use a pantie liner.every time you use the bathroom change the liner.and feminine wipes to clean the area and reapply the ointment.
I'm not sure if this qualifies under relationships so I"m going to defer to more of a medical-oriented forum for this one . . .
