I've been leaving multiple womens cum and cum juices on my sheets for 18 years now, and still haven't washed them yet. My lucky sheets, you know?

But seriously, door knobs, things you touch, etc? Dead serious, I have never washed items I touched afterwards like a doorknob. Wtf? I have never had a girlfriend get UTI, or even get sick from it. I'd say male cum is probably the most cleanest juice from the human body. It makes a damn baby. The woman's body, also makes a damn baby. You were stuck inside juices for 9 months, while your pops probably squirted his juices on your forehead for 8 of those months, and you were still born right? I do not think you need to worry about juices that literally form new human life as something that needs to be "cleaned". Now, if you fingered her ass, different story. Wash your hands and the things you touch.

But even then, you still wouldn't get sick. Ice in a restaurant has more bacteria than your toilet at home. Google it.
