Japan Libraries of VR & they also have a 3d section http://www.javlibrary.com/en/vl_genre.php?g=aaua and this site: https://pornav.co/jp/search?q=vr Although Japan subjects can be creative and unique, sometimes the 3d separation is messed up, not necessarily by to much side separation but by up and down separation that can't be corrected by the VR Players SBS Offset (maybe Skybox player should add Up and Down Offset to correct that). Also they have a habit of going to close causing double or blurred vision that way as well. We won't even get into the annoying Mosaics Censorship that ruins the scenes and how they fail to work around that handicap. Lessons we learn: teach the subject performers to understand and recognize distance to the camera to find each cameras sweet spot. Producers should know that sweet spot distance before cross eye or blur sets in and pass that knowledge to the model doing the scene, even sometimes using tape or visual markers not to cross that distance. Japan perfected the kiss scene, but failed a key added feature that would sell the scene, that being hand motion to simulate jerking motions which in VR goggles really makes it more immersive a reality experience. This is why I am surprised nobody has taken DB Jerk or cleaning work motions into a VR production. Package that motion with ASMR ear to ear and you have a genre that will be very popular and you'd be able to get many times more models in the industry that don't want to do hardcore, but will do simulated actions. There's many more 2d genres and concepts overlooked that are perfect for VR, just go down the line and think about every type and ask yourself, would that convey in VR and be many times better or would it be lost in VR?
