check it out, who would have imaged an article name like that?! islamic law and oral sex?! what is next? anal sex with the pope?
Indeed, it is quite clear that wikipedia has many pornographic pictures, and articles, it is practically a free pornographic sex site for all the horny teenagers who have no money to pay for those sex sites, all children are welcome to check out the wonderful pornographic world of wikipedia, full of sex, free sex for all, no age limiatation at all.
Some libraries blocked some adult sites, well, welcome to browse wikipedia, even if you are under 18 or homeless, wikipedia is not blocked on any library computers.
It is simply just what exactly I was in search of.
