zero experience but i remember watching youtube on it. my eyes kinda hurt after a while and i just watched youtube normally. same effect may happen. i’d imagine you’d have to watch vr specific porn which may seriously limit your available material.
when i first got psvr i used it a lot for that. i really enjoyed it, especially with good spatial headphones. only reason i really stopped using it was the hassle of setting it up just for the 15-20 minutes of gooning on it
