To be clean is a highly attractive feature for most of us, lank greasy hair, smelly beards,dirty fingernails, unless of course he is a mechanic or his job entails this they still wash.to be dirty whilst in a relationship is a major insult to the other person.
To not wash the smelliest areas and expect a kiss with bad breath, or a bj with a stinky penis, these are just major disrespect for the other person.
Why on earth people cant keep clean that are capable of maintaining themselves should not feel any pleasure or expect any from anyone else.
Its just selfish inconsiderate behaviour
A mistake is always forgivable, rarely excusable and always unacceptable.
Robert Fripp
