From Dr. Halat’s website.
Should I be bothered that his math is completely wrong? To take the more obvious example, if you have sex with 2 people who’ve each had sex with 2 people, you have been exposed to a minimum of 4 people, not 3 (unless your two partners just happened to have only had sex with each other). The math gets worse from there…
But the man has a microscope and a lab coat, so I shouldn’t complain.
This graph, which has been fairly widely circulated (along with considerable debate about it’s legitimacy) is from the Wellesley/MIT student paper Counterpoint. The original article is no longer online, so it’s hard to say how scientific it was, but everything I can gather suggests that it was at least based on an actual survey. For me, the points of verisimilitude are the relatively shallow slope of the curve, the fact that “undecided” was included as a major, and the duplications of 83% (10 in 12) and 50%.
Also, the order makes sense to me, but YMMV.
The ancient “fruit system” of breast taxonomy. But…what the hell are these women wearing?

Before I shut up about the variety of breast shapes and sizes, we gotta discuss implants. Despite a history of problems, breast modification is the most common form of cosmetic plastic surgery, having beaten out liposuction about four years ago.
Although Dr. Wiesloph’s men scuttled the zeppelin, our agent managed to escape with the schematics for Plan Q.
Forms, Dimensions & Angles

This graph is from The Thang Blog, which brings up such stumping questions as whether a Jewish transman should get a neo-penis with a foreskin and then get circumcised.

Nothing is sexier than moving average plotlines.
Although the 2003 Massachusetts backlash making this whole graph look kind of like a cock has to get an honorable mention.
From the wonderful Yes Means Yes blog.
So, after I wrote this, Murre has been interested in clarifying my love/hate relationship with different toys, and in particular toys that…ahem…go up my ass. The case in point was bananas: Murre loves fucking me with bananas, and I find it both humiliating and not-so-sexy-by-itself. (Mind you, the fact that she makes me do something I don’t find sexy is itself sexy. Aren’t submissives easy to figure out? Yes we are.)
Hence, I am presenting this easy-to-understand diagram, which contains (more or less top to bottom):
Enema kit
Inflatable butt plug (Never had that happen to me)
Popsicle (NHTHTM)
Icicle
Cock au naturel
Butt plug
Gorgeous strap-on
Peacock feather butt plug (NHTHTM)
Anal beads (NHTHTM)
Ponytail butt plug (NHTHTM)
Anal speculum
Daikon radish
Banana
Carrot
Kumquats
Chain, ouch
Steel ball
Baby Jesus Butt Plug (NHTHTM, and never will)
Obama dildo (NHTHTM, people are weird out there)
Not on this diagram due to afterthought: Fingers, fists, peeled ginger, tampons, ice cubes, vibrating plus, and those weird prostate massage thingies that look like they sat out in the sun for too long.
