Bacterial vaginosis. It's normal to have a healthy mix of bacteria in the vagina. But the wrong bacteria growing there can lead to an infection. Besides itching, other symptoms that come with bacterial vaginosis are inflammation, burning, discharge, and a fishy-smelling odor. I have vaginal itching, but I don't have discharge or odor. Skin conditions can be with or without rashes. A fungal infection, like jock itch is also common.
