Well here is my 2 cents (didn't read the entire thread, just page 1 and 3)
Beauty is indeed subjective. This may sound insane to some but i read recently some peoples saying Sydney Sweeney would be "mid" without her breasts. Sure not gonna lie, i love those bazoombas

but even if she was a B-cup she would still be a very attractive woman. There is BBW escorts that are succesful while a lot of clients wouldn't book them because they not into that. At some point i think subjectivity plays a big part.
There is also how you may be influenced by a person. If she gives you a superb experience, of course you may feel more attraction to her. Lets be honest. Lets say she was exeptionally nice and great in bed, how would you feel saying "well physically she was slightly above average, but her service was great". Of course you can't say that. Not only cause you risk alienating the person in wanting to see you again, but also it just comes out rude imo. For the peoples who been married here, have you ever told your wife "yeah the neighbor is way hotter than you, but don't worry, i prefer your personality". ... lol
I think looks also changed a lot since my early days. Of course there is still the "stripper club look with big fake tits" but good luck finding it without tatoos. There also seem to be less of them in agencies and instead more chasing the big bucks as indies. Maybe im wrong, i mean i don't book 40 times a year like some, im in the single digit, but its just what i notice by browsing the sites etc.
As for the privacy aspect and tatoos, well its a bit funny. I never hidden that i am not the biggest lover of tatoos. I did book plenty of tatooed providers and it will not be a "blockade" for me, but i would always think she would look even better without them (or if it was just a few well placed). But funny enough it happened a few times i was just browsing twitter or instagram and was like "wait a minute..." and recognized someone because of her tatoos.
I get they can be hairbrushed out of pictures, but if you actually meet the person and remember them, well... And altough some ladies may be extremely good at keeping their socials more private, all it may take is one friend that is not as "private" posting a pic of them and there you go. Its also very easy to make connections when you know some SPs are friends etc. In this heavily digital era, its getting harder and harder to keep privacy.
