==whose "community standards" are these?== 
 Plainly, a number of fellows are having great fun adding pictures of their penises to this article, and have not the slightest interest in increasing the encyclopedic value of Wikipedia thereby. 

 However. To pretend that there are established "community standards" on Wikipedia that discourage nudity and sexual depictions is totally false. CyberAnth links to a proposed Wikiproject guideline which he is actively involved in debating. A few things to note: 
 * It is not Wiki-wide, but applies to the Sexology and Sexuality Wikiproject, of which this article is not a part (but actually...shouldn't it be?) 
 * It is not established even for that project, but is still a set of proposals for discussion. The page heading states "References or links to this page should not describe it as 'policy'." 
 * On November 30, Wikipedia chose to feature the article History of erotic depictions on the front page. Leadership of Wikipedia is apparently not shy about being perceived as sexually explicit by casual visitors.
