I’ve always been curious, because I’m not fond of underwear, but I don’t know how people make it work. Wouldn’t you have to wash the trousers every single day? How else would you keep them fresh? Do you use special deodorant for the area or panty liners on the trousers?
Tell your story.
You shouldn’t be intensely itchy down there like that. It isn’t normal. Honestly you should probably go to a doctor because you might have some sort of infection. And please change your underwear. It will probably help with your itching.
