It really depend on certain point of views. I personally think there was a lot more stripper/pornstar looking SP back in the early 2010s. Maybe there has been a resurgence lately, or maybe its because you focuss more on indies, but in agencies, i would say there is more natural breast than fake.
I agree tough that body modifications of all forms seem to be more prevalent. Ink is the most repent. I don't mind some personally, but in a lot of cases i would prefer her body if she didn't had it, or so many, even if i find her attractive even like that. Its not just SP, its everywhere, if you look at pornstars, even the old pornstars who come back or do something else but are active on social medias end up very inked even if they are in their late 40s... Actor Sylvester Stallone got all tatooed up very late in his life. With instagram models i would say its maybe a bit less, but there is still some that have a lot of ink. After that, there seem to be a few things that are popular wich i find absolutely ugly (sorry, just personal opinion), like the metal balls in the cheeks. Seriously, what does peoples find pretty in this? And when you get tired of it, you risk having a deformation/scars. Another thing is these huge streched piercing in ears...
I do agree that tatoos should be part of advertisement these says, because they occupy a huge place. When i see someone that has either none or very fews im almost shocked lol. Maybe its because how we are conditioned. I mean i LOVE a tribal tatoo on the back because that remind me of KRYSTAL STEAL getting it doggystyle in my early days of porn. But other form of tatoos remember me more of "Uncle Mitch" on his Harley...
Same for the hairy private parts. When i started watching porn it was either just a stripe, bald, or at worst a little V. Very short too. Even tough Montreal SP scene seem to be so far spare, in the US especially in porn its getting very harder to find a bald vagina. At some point i wouldn't be surprised to see SPs advertise this as well.
As for the rest of your post, yeah onlyfans... It made possible for anyone remotely attractive to shoot their own porn easily (coupled with the cellphones we have these days) and keep the majority of the revenues vs getting a 800$ one time payment for a scene to a pro shoot. Its insane if you look at the hot quebecers who does OF vs the ladies in general who appear on Pegas or AD4X. Its night and day to me. But do you enjoy paying 50$US a 10 min scene? I sure don't... But as with anything some guys have deep pockets. Wich also explain the crazy inflation of indy prices. I mean ever since i started i saw agencies go from 180 to 200 to 220 and eventually 240. Some are 250-260 but its often just a jump of 20 or such every couple years. With indies its jumps of 50-100$, and we now have 600$/h indies in Montreal. I never taught ill see this, at least not until another 15 years from now. The 400 to 500 jump happen so not long ago and now another 100 jump... woaaa.
But again, clients with deep pockets. If you follow SPs social medias etc its not rare you will see them brag about having gotten a free 500$ gift by interact just for fun, or stuff like this. If i was a rich millionaire and throwing a few hundreds sometimes would mean getting priority bookings and attention and other favors, would i not do it? So its hard to blame either side there.
But ME, i still see 400$/h as the ultimate prenium price. Way above the market... Even if there is VERY few indies left at 300$ or less.
