My first thought is
" I blame the parents" My kids by age 2 knew how to wash all areas of the body. No grown adult should be nasty, cheesy or smuggling smegma.
Anyone who plans to hobby male/ female should be informed of proper hygiene and of course simple "tell tale" signs that there may be a medical problem.
"taste test" is best method for us ladies. YES I do taste, I want to make sure it tastes delicious not like a scented soap.
**Many ladies have towels, wash towels, toothbrushes, toothpaste, soap & mouthwash available**
