I mean I just wash the whole area with soap. But I don’t go in side with soap just like the outside
Same as these ladies. Nothing inside and just my usual soap outside (but I do use natural soap for sensitive skin) but even when I didn't it's still what I did.
I had folliculitis from shaving - you need to take a break if your shaving too frequently, change shaving heads every time, or choose a different method of hair removal and make sure your underwear is breathable/isn’t tight . I used to just use a little soap on the outer parts & occasionally I’d exfoliate the inner thigh crease area.
i only ever use water on the inside areas, the outer parts i just use my regular body wash
