I had a profile on here, and was very active on it, but haven't got back on since the football started.
My experiences have been generally good, but with some caveats.
The system, where you buy credits to "unlock" the initial messaging stage is a bit irritating and I'd rather it was a flat rate monthly fee, although saying that the credits aren't expensive. Also the site is awkward to navigate and in my opinion poorly designed.
As you can imagine you get girls on there who are typical sugarbaby types, some who are looking for proper relationships and a lot of foreign girls (at least in London) new to the city just looking for a night out.
You can see what kind of relationship/encounter/arrangement/whatever that they are looking for on their profile but a lot of them just leave them all selected so not especially helpful. Oh and if you think some of the girls on AW write some garbage in their profiles, I have to say this site really takes the prize for pretentious self-important drivel.
You have to pay for the "date" so there's the risk of throwing money away on a coffee if you aren't clear what you want. Luckily the payment is in cash to the girl so although you make the offer and she accepts, you can message first to see if you actually want to meet.
My policy, for better or worse, is to make a £50 offer and no more than that, and then at the messaging stage state quite clearly that I'm not looking to set up an arrangement (not paying for her to go shopping ffs) but am looking for a sexual encounter. If you do this you will get more than a few fuck offs I can tell you! But you will also weed out the chancers and wasting your own time. The number of girls on there purely looking at selling sex is I would say quite low, as in that's there whole reason for being on the site, there are easier ways of doing that clearly, but a reasonable amount are up for negotiating a fee to meet and have sex with them. I've had a few where we couldn't fix a fee that suited us both, and others that wanted what I felt were unrealistic things first (shopping, absurdly pricey restaurants, trips to swanky but ultimately quite dreary central London bars).
I've had 4 "successes", all students, where we went for a drink and then back to mine for sex. One of them I am still seeing on a casual basis with agreed fees for sex, the others I or they wanted it to be a one time thing. I met 2 other girls from there who having planned to sleep with I didn't, the first because in the flesh neither her nor her personality were very attractive and the second seemed like a person with quite a few mental health issues and I felt it unwise for me or her to go through with it.
So yeah, if you put the effort in and spend some time on it, you'll get what you're after, but I think it's important to be clear very early on with the girls what you want otherwise you run the risk of wasting time/money. For being honest you'll get a whole load of abuse from some girls, but ultimately you're just weeding out the ones who aren't going to offer you what you want anyway.
