Have been using VR Porn for years, it is amazing. Right now it is still a niche. The equipment is rather expensive, especially if you want to shoot in VR. I am positive, however, that the technology will become cheaper, easily accessible and more affordable in the future. I would love to have VR privates with my fav girl!
Also, to me, immersion has been better in the beginning - now my brain is acutely aware of the two missing sensory inputs - smell and touch. It is as if it keeps telling me "stop fooling yourself, it is NOT real". The best VR gaming experience I can recommend is Elite Dangerous, if you want to pilot your own spaceship.
