Alot of seeking girls do end up on aw over time. But would i call them escorts - not really/not yet. But they are on that path.
Aw is like getting your fruit and veg from a supermarket, pick up, pay, get the fuck outta there.
Seeking is like growing your own fruit and veg, takes time and effort, works out alot cheaper and is alot more satisfying.
I would say if you propositioned a random girl on SA (especially someone new to it) with a chunky amount of money to rim you, you wouldnt get very far. But you could drop that on a aw reverse bid and get alot of responses.
The girls that get creeped out by these messages are the types i used to get into arrangements with. Being younger, more on their level and up for showing them a good time meant i used to get into really fun regular meets, more importantly alot more bang (literally) for my bucks.
