Unfortunately, there aren't much VR videos around. Maybe it's because the VR industry is just starting to blossom?
https://www.sexlikereal.com/ (yeah, NSFW, doh) is an accumulator site that focuses on VR content and takes BTC and even LN-BTC as payment.
No clue about the premium you'll pay by getting content there via buying it directly from the studios, but it's worth a look / comparison.
