I don't think content is the problem, it's awareness of how immersive VR porn is.
And don't focus on short form content (only short-form marketing) - short-form content is a 2d thing which can be viewed purely for casual entertainment, but VR content has to be worth the effort of wearing the headset (and setting up Handy etc). VR is like Imax, it's an event - while it can be fun it is NOT casual. Not until the tech makes it so with super light and comfortable AR glasses that you wear all day.
If you want to grow your audience, it's an awareness problem to solve. Make it cool and fun with short-form tiktoks, sponsorship and porn ambassadors etc (like Redbull or whatever) - this is a massive task as you're basically de-stigmatizing not only porn but VR porn so it's going to take time and ingenuity. Let's face it, Meta with all their resources, STILL struggles to convert gamers because VR has to be experienced in person. It's not like you can really have an SLR tour bus visiting malls across the globe to show people what VR porn looks like.
So 1) how do you make the idea of VR porn fun and socially acceptable, and 2) how the fuck do you get people to try it? How?!
Have you approached Joe Rogan to be featured on his show? He's already talked about VR porn so a logical place to start. You really need a spokesperson who can engage with that kind of celebrity and promote the concept. You need a Musk / Zuck / Jobs to go out there and spread the word with charm and eloquence.
