At this point just keep the area clean. It may help if you use a warm moist paper towel or washcloth to hold on that area while you use the bathroom which will help with the burning. If this is no better by Monday or seems to be getting worse, you may want to be seen to have it checked out. But generally it should heal up in a few days and not be so sensitive.
