Not washing properly
The ‘proper’ way to wash in the shower is to go from the head down, and to scrub. Loofahs aren’t necessary- your hands will do- but to properly lather your soap and get it everywhere is the proper way to wash. In particular with intimate areas, scrubbing removes all the build up of bacteria to prevent infections, and can help maintain a healthy pH to prevent unpleasant odours. Scrub a dub dub is your new mantra!
