Okay, so we don't need to spend much time on this, but I feel I need to address this issue. Not every woman knows this important tidbit of information, so I'm going to say it plain and simple to avoid any confusion.
When you go to the bathroom, you need to wipe from front to back. Are we clear on that?
The reason being you want to prevent the spread of intestinal bacteria from the rectum to the urinary tract, and hopefully prevent painful and annoying urinary tract infections. If you think about it, it makes complete sense.
I'm glad we've cleared that up. And I know I don't need to tell you to avoid buying used toilet paper. Good god.
