When I shave “down there”, it’s typically fine for about a day or two; smooth, soft, and free of any bumps or red marks. However, after two or three days, I get what looks like razer burn. I assume it’s not because razer burn typically happens immediately after shaving. It’s also not any infection or STD, I’m clean. Are there any types of lotion, oils, or perhaps any other way of clearing this up?
