i do feel like there is a distinction - the more down to earth looking ones seem to enjoy the sex side of it...the more dolled-up ones enjoy the lifestyle it affords them. this is of course a sweeping generalisation.
lot's has changed in the 15 or so years i've been in this game. i'm sure there's guys who have been in the game longer who'd talk about the halcyon days when they would get up to all sorts...
When I first started punting you couldn't get a WG to allow FK, or RO, OWO was pretty rare if I remember correctly.
Nowadays that's all pretty common and you can get CIM, Face Fucking, Receiving rimming, even Anal aswell, sometimes for no extra charge!
I may have been unlucky, and not getting good WG's at the start because there was no UKP. But if there was some golden period between then and now, that definitely passed me by!
