I washed my hands before I typed this.
I like to think of my blog as a public service. The information I present is so diverse that I doubt there's a person alive that won't find some kernal of useful information here. So, I present to you, Jackin' World: "The Ultimate Male Masturbation Resource". But, you say, I don't want to look at porn! Well, it's not porn, it's instructions. [Link via Idle Words.]
In a similarly useful vein is All About My Penis. (It's not my penis, mind you, it's someone else's.) And because I don't want to leave out the women, here's All About My Vagina. [Link via Kristiv's Weird Existence (an Icelandic blog in English!).]
Update: I've been informed by Sara of Corn Smut that there's a sort of female equivalent of the Jackin' World site called Clitical.
