Someone (a friend) should tell him to wash it!
no, that's unusual.
Legend says the French wash from the waist down and the Anglos (including us) wash from the waist up. There are plenty of American guys out there who are uncut and don't know they have to wash it after peeing if they want to have sex.
Exactly, it's all about education and I understand it might take guts for an escort to tell his client to "please wash it" but the alternative might ruin the whole date.
