Seriously? Doomed to fail? I keep buying more and more memberships in more and more sites. I rarely bought flat porn in the last 10 years. I started buying headsets way back with the Oculus DK2, even though only flat POV videos were available.
In addition, I keep buying new interactive toys and headsets. When they come out with some of the new stuff,
And I am constantly experimenting with new ways to make it more immersive for myself (e.g., self hypnosis, binaural beats playing in the background, doing a little weed and/or other substances, etc.).
BTW, I WOULD feel like I'm cheating on my wife, but I'm very upfront with her about my usage and she's fine with it.
All that said, most the studios are starting to get in a rut with their scenes. Why did the need to go through each possible position in each video? Given the vast number of videos, there is room to meet niche demand, without each video providing something for everyone. For example, one type of video I'd like would be if it had only seated blow jobs and seated cowgirl. I almost always skip doggie style and reverse cowgirl scenes because I want to see breasts and face. Why does nearly every video have to have these types of scenes?
I'm going to say that there are a few exceptions to studios getting into a rut--for example, for me, VR Edging seems know how to mix it up, even though they specialize in only one type of scene. They are my favorite--and yet I know that some other guys HATE VR Edging videos.
Okay, I went off on a tangent.
Back to the original question: No way is it doomed to fail. As headsets become less expensive and the VR apps become easier to use, I think more and more people will want to use it.
