Immersion works really well on me, which is why I love VR porn so much. It feels more personal and close.
Though that being said, there are some things I don't see often, especially in GFE-scenes I miss them.

Cowgirl grinding/straddle. Instead of bouncing and pounding away up and down, I would like to have some back and forth. That's also usually how girls/women in my life most of the time did it. Here's a random example I googled:

The guy sitting upright you can ignore, it's about how the girl moves.

Another one resembles this but also would be more in line with what GFE is or should be.
Cowgirl with girl leaning over you, her hair and breasts dangling in your face.

As for missionary, I would also like it if the viewpoint was face-to-face, much like my previous example but with the guy on top.

I've seen all of these in VR, but it's often really short and the scenes that offer this are far and wide between. Even with all these studio's producing content.

And I think it goes without say they would have to be funscripted 😉 🙂

I agree especially about the face to face missionary. Czech VR Casting is sometimes good for the face to face btw, although it could be a little closer.

I would love to see more of the guy standing/kneeling and the girl on a bed on her back or stomach giving him a blowjob so you can see her whole body. On her back is something I never see.
