What Does Sore Red Patches With Slight Swelling On Inner Thigh Indicate?

I have two sore raw red patches on my on my deeper inner things and bottom of my vulva. It doesn t it that much it s just sore and irritated, slight cracks. Slight swelling. I shave and my hair is growing back so that could be adding to it. There no weird discharge or odor. I am recently STD tested so that s not the concern but I am sexually active. I ve also been tested for herpes recently so that s not it either. Help?
