What other purpose do you think those animated six mods (that have a place in the top 20 mods of all time on the TES and New Vegas Nexuses) serve? I'm pretty sure "because they are mature and like mature content and are totally not infantile, you are!" is not the answer.
While we're on the subject of the evolution of society, having to attach six to [censored] everything will eventually result in http://4.bp.blogspot.com/_9vYa3gq9w_k/St0-87i5HXI/AAAAAAAABj4/pFY-HKKFxNU/s1600-h/idiocracy-starbucks-exotic-coffee-for-men.jpg.
Because six and nudity is the same thing, that's just evidence... Everyone who goes take a shower/bath is doing an intensely perverse activity... :facepalm:
Just look at painted art. It was in its golden age, that there were the highest number of naked/erotic paintings.
If a game handles it in a good manner, it can become part of a living world. the way things are implemented is what counts, not the feature itself
