In my opinion nudity is not porn and never has been. To me a fellow, young man or man, that gets aroused by attractive women virtual or real is quite normal. We are hardwired to respond in this way. I consider folks who experience guilt that turns into self-hatred over feelings brought about by nudity 'perverse or perverts'.
You know what? Your absolutely right! All this time I've been getting my self off on Nalu swimming around nude and would feel completely guilty about it. I see now though, that taking care of my business to a nude 3D model is O.K!
