Have this moist light orange/red liquid when I wipe. And the substance appears to secrete randomly, does not appear visible after taking a poop. Vast majority of the time it will be present when it is hot outside and I am walking, and I feel sweaty down there. Sometimes I feel overly sweaty down there so I go to the bathroom to wipe, only to find that sometimes it is a light pink or a very light orange/brownish color. What is going on?
