Yeah, we actually have sweat glands in that area, and they get busy in hot weather. Some ideas: 1) Blow dry around the lady parts after bathing or showering to make sure all gets dry; 2) Do use the Gold Bond powder that was suggested; 3) Change your underwear twice a day.

I was surprised to read that most of the "feminine smell" actually comes from the sweat-gland area, not from inside us.
