It is what it is, sex sells as they say.
But not so much in domains, i wouldn't go near an adult domain name personally with view to making a ROI, how many adult domain sales do you see nowadays go for big money? (edit just thought of one ass dot com, but is that an adult related domain sale?).
But if i had my pick on any VR domain to 'develop' with view to making money (traffic wise) then without doubt VR porn is the one.
But the best keywords you can have for me in virtual tech are 'video' and 'games' - I'm not just saying that because i own 'video' i said it before i even owned the domain (hence why i targeted it), but 'video' and 'games' are the 2 areas that are tipped to bring in the most revenues in virtual tech:-
