Just to add to the article, most of virus or bacteria that create problems are found at the orifices (holes).

For guys, the whitish crud or layer of film at the head of the penis when we retract the skin is called smegma. It has been found to be carcinogenic. So wash your penis with soap and water regularly.

The other obvious place is the anus. The unwanted stuff of the body gets booted out.
