As far as this topic goes - I hope most folks realize that the women in porn only do this for money and/or to use it as advertising for their other streams of revenue (OF, escorting, sugar daddies, etc.). Whether they truly like any/some/all of the stuff they do is mostly hidden behind the scenes/camera. You'll never truly know unless you actually know them and they give you a legit answer that isn't bullshit. Of course, you'll have some women who naturally love having sex (including whatever kinks/fetishes they are into) on camera and being watched - especially if they can get paid for it. The percentage mentioned in this thread is irrelevant, but you can bet most women would prefer to do only pussy penetration scenes if they could. Fuck, they'd probably prefer just to be nude/solo. Heck, they'd probably like to get paid just for them to be in your presence lol
I like watersports (In porn and also real life), but I only like it when the model is actually into it - this includes other porn acts too. When a model has a facial expression of hesitation or disgust, the scene is a bust and they should have done a scene without it as it breaks the flow in my opinion. Unfortunately, for
A LOT of the scenes on this site, you can usually tell a good portion of them don't like it.
There is only a handful of models who actually appear/look like they like it. This also includes the models who can actually swallow piss too. It's why I have that annoyance with the tags. Most piss scenes are tagged as piss drinking/swallowing, but they don't actually do it. Most of them just use the strategy of letting it spill out of the month and pretending to swallow.
Like the other posters mentioned already, you can have this same discussion on any other porn act (Facials, Cum Swallowing, Anal, ATM, etc.). As much as this forum loves anal (including DAP/TAP), I got some bad news for ya
Money will open the doors as most people have a price on what they will be willing to do, even if they do/don't do it in their personal lives. Let alone if they like it or not.
Same concept can be applied to Sofa Weber - You think she likes anal based on her consistent facial expressions and hesitations/stiffness? She definitely doesn't like piss either. These types of girls may meet the aesthetically attractive metric, but you know for damn sure they aren't doing it cause they like it.
Don't forget your personal lives too. Your partner likely doesn't like everything you are into, but they may still do it cause they like you or like seeing you get off (and vice versa). Not much of a difference here, other than incentives at hand.
