Aw was originally created as a specialised bareback directory.
I don't remember it quite like that and nor do I remember Adultwork 'promoting' bareback especially, only that it was the first to allow those who were offering it (alongside all the other
perfectly legal services they offered) to advertise the fact openly, rather than the adopting the nauseatingly prim and hypocritical approach of other directories at the time and banning any ad which mentioned unprotected vaginal or anal sex whilst welcoming ads offering unprotected oral.
IIRC the site was set up as an all-encompassing platform offering a mishmash of different things including webcam, porn pictures/clips, phone chat and in person services. Not that it's in any way relevant to the thread topic
