I need help.

I begin my freshman year this Wednesday, and I don’t know how I’m supposed to wash my ass. I’ve grown up washing my butt using a large plastic cup filled with water, and then pouring it onto my butthole, and using my hand and fingers to clean it. Afterwards, I’d wash my hands with soap.

The issue is that I’ll be sleeping in a dorm apartment that has communal bathrooms. In my home bathroom, the sink is directly in front of the toilet, so I can refill the container as I wish. But I can’t do that in college.

What’s the cleanest and best way to wash your butt in college? I can’t fathom how people wash their butt using a dry paper towel. HELP ME!!!
