Clear odorless discharge from my butt.

For a several weeks now I have been experiencing a clear white watery discharge from my butt. The stuff seems very caustic and it burns the skin in the area around the outside of that vicinity. Ususlly it is not a whole lot but one day it was so bad I had to stick some toilet paper in there to try to soak it up. I had to change it several times and it soaked the back of my pants. (embarassing). I do frequent master cleanses, use Dr. Schulze 's Superfood and Intestinal Cleanse #1 and #2. I do a moderate dose of food grade H2O2. I've been doing all these things before this problem started. I'm not sure what this could be. I've been pretty healthy and never had anything remotely like this before. I'm sorry if this isn't the right forum to post this on, I wasn't sure where to place it. Thanks in advance.
