For me it's a resounding 'YES', it can and definitely has affected my standards and expectations for sex and dating with non-escorts.
I'm currently seeing a beautiful blonde from Finland; she's nearly 10 years younger than myself, friendly, always smiling, and in my opinion, every bit as good looking as many of the ladies that advertise on this site, and even better looking than some of the escorts I've seen in the past. But even though her and I have already slept together (and have even gone on a shopping trip to LaSenza where she gladly tried-on and let me buy her one of the naughtiest outfits in the shop), I must say that we kind of had a 'false-start' when it came to sex, and I think it was almost totally me and my experiences with escorts that was the cause of it.
What can I say? The first time we were in bed together, despite her being really attractive and horny, I just wasn't as 'stimulated' by the overall experience; I just wasn't all that excited, and though she's very happy to be on the receiving end of things, she's been really shy about 'giving'. We've talked about things now, and she's told me that "all I need to do is ask" (which I must say has worked out well for me
), but there certainly was that underlying expectation there that she would just sort of know what I wanted/expected, or that she would be sort of bold and straightforward in bed without me having to ask, the way things typically are with escorts.
I suppose I've spoiled myself with the level and quality of sex that escorts provide, and felt a bit let-down at first when things started with this girl, since it has been 90% me directing/guiding our sexual ecounters, whereas with escorts it's often them that takes the inititive.
So I've just needed to make a bit of effort to reconcile my expectations with the reality of things again, it's just taken a bit of time to do so.
