I had success with SA, but I get success with Tinder. The best way to view it is a mix of adultwork and online dating, if you aren't able to pull any women using online dating (or didn't want too) you won't get on well with SA.
That said, the two girls I hooked up with were early twenties, and nothing like a woman you would get on adultwork. They buy into the "dream" of a sugar daddy and from my experience the women do not sleep with lots of men. No worse than your typical Tinder slut in a big city, and they will be nowhere near the numbers of a working girl.
My advice is to put decent pics up, get chatting, but ask to move to Whatsapp ASAP. If they give you their number there is a good chance of success, if they don't or they stall, delete and move on, it won't happen. Talk about logistics early, and what you can offer (say you'd love a pretty little thing to take to a nice hotel break, or I live in a 5 bed house and would like to go out for dinner and back to my house for a few drinks. Say you are happy to meet for a coffee first, this will make her feel more comfortable, and saves you the cost of dinner etc if it falls flat on your face.
To summarise:
1) treat it like dating
2) ask for number to chat on whatsapp and use this to filter wasters, no number = delete and move on
3) sell them your 'dream' - what you want
4) propose to meet for an hour over a coffee first, it'll cost you £7 for a coffee with a pretty girl and if it goes well you know you're gaurunteed before you start buying dinners etc.
Do this, and you can have a sexy night that just isn't possible on AW. If you're above average looks do it all for free in Tinder, I've got a massive Google contact list with whatsapp numbers of tinder/bumble/POF girls around Bristol, Newport, Bath etc., about 700 in the last 2 years 😅.
Peace and love
