diwanga I did start out like that too.  I stood up when the stunt cock guy was standing up, lay back when he was laying back etc.  Over time though I got lazy and just started using the tilt function to adjust my vision rather than physically moving.  From interacting with others, I would suggest that many others watch VR sitting or laying down rather than physically replicating the scene.  It’s cool if you do act out the scene, I totally get it.
I’m actually one of those who strongly advocates for more standing blowjobs and more traditional standing facials.  Even though I watch these scenes laying on the bed, I absolutely don’t want scenes that spend the whole time with the stunt cock laying back on the bed, I hate that.  Doggy style is my favourite position in porn and in VR porn so I want the guy to get up off his ass.
