(undent)The proposed external link may be rejected here, or it may be accepted.  Either way, I hope people will see that it gives readers some choice in the matter.  It let's people know what they're going to see, and lets' them choose.  In contrast, people will come to this Wikipedia article expecting a typical Wikipedia article, and will instead have no choice but to be looking at a guy sucking his erect penis while displaying his asshole.  Are videos next at the top of this article?  Many visitors here will not know what the word "autofellatio" means.  Some of them will have clicked to see a random Wikipedia article, and some will be trying to get info about a word they have not heard before.  Other people will know what the word means, and will be looking for information other than unexpected pornographic photos.  The reason why even hardcore porn sites give people a choice in this matter is because the image like the one at the top of this article is not something that a lot of people won't want to see, and they should be able to choose.  I distinctly do not like the attitude that readers shoud have no choice.  It's an aggressive stance for us to take.  The idea that giving them a choice is anything akin to "censorship" is false; the word "censor" implies removal or suppression.  I've never suggested any such thing.
