I mean, general consensus on here is that a girl that trades from the street is "dirtier" than a girl in a penthouse suite in Mayfair. Maybe, who really knows?
No guarantees. But I've met really clean street girls (3 actually) who almost certainly weren't alcoholic drug addicts and I've met less that clean girls via AW, no offensively smelly vaginas so far thankfully but the odd few with halitosis, one with BO and many who clearly hadn't just stepped out of the shower.
On the whole your average street girl is far less clean, but they live a far more transient life. Their priorities are money, heroin, money, more heroin, money, alcohol, money, food - in that order which leaves no room for personal hygiene. Catherine is right, if you smell it you really don't want to go there.
A girl via AW has never left a used tampon in the passenger door bin of my car either, as a street girl once did. Apologies to anyone eating.
