Orgasms during intercourse… Women’s experience from our sex survey. 

From a study of young women who were raped while they were teenagers. For the abstract, click here.

Photo of a University of Michigan frat party taken by Stanley Kubrick in 1949 when he was a photographer for Look Magazine. Kubrick went on to become one of the greatest movie directors of all time.

Some of the reader comments from the Shorpy Historical Photo Archive about this photo:

—”I guess she’s about 83 or so by now. What a hottie!”

—”The tortures through which women’s breasts were put by the dictates of glamour in those days continue to astound. She’s clearly wearing a “circle stitch” bra. I was a young adult before I discovered it is possible to dance with a young woman and not suffer injury to one’s sternum.”

—”Not sure if these kids were any better behaved than the kids now, but they sure dressed better.”

—”I’d say it was a ‘make-out and smokin’ party’ (no food and no drinks).”

—”[This] depicts an informal party at the Theta Xi frat house…  Apparently the human interest angle was that men usually did this for women, not vice versa. That fraternity house is just up the hill from where I took a city bus every weekday morning en route to law school.”

These young women are strawberry poison dart frogs. They are part of the poison dart frog species, which got its name because indigenous tribes in Central America would use the toxins from the frog’s secretions to poison the tips of their blowdarts. (Pain killers have also been made from the frogs’ secretions—with one being 200 times more powerful than morphine.)

Researchers from Germany, who were apparently looking for an excuse to spend time in Central America, studied the mating habits of these frogs in the wild. What they found is that the female frogs expend no effort whatsoever in selecting males. Instead, these brightly colored ladies will go for the nearest amphibian who is willing to hop on and have at it.

This contradicts the basic tenants of evolutionary psychology, which state that the females of any species will try to find the fittest males to breed with. These girls gone wild don’t care who the dads of their little tadpoles are going to be. They just want to get the deed done while expending the least amount of energy.

Hypospadias is a condition where the urethra (tube you pee through) doesn’t go to the end of the penis. In mild cases, it comes out near the end of the penis, but not quite. In more severe cases, it can come out anywhere from below the head of the penis to the scrotum.

Hypospadias is one of the most common birth anomalies there is, occurring in 1 in 125 to 500 boys. The possible reasons range from genetics and environmental pollutants called endocrine disrupters to obesity of the mother during pregnancy and diet during pregnancy,  including a vegetarian diet or a diet lacking in meat and fish.

It makes sense that cases of hypospadias occur on the bottom side of the penis where nature left a long seam. When the penis is forming in the womb, nature zips it up along this seam. The urethra goes inside the chamber of the penis that’s just inside the seam. With hypospadias, the urethra got caught in the zipper like a penis will if a guy zips his pants up before it is safely out of harm’s way.

Hypospadias is usually a minor birth defect that often looms far more massively in the mind of the guy who’s got it than in mind of a potential partner. There is nothing about hypospadias that makes a man any less of a man or any less of a lover, although sometimes it results in a condition where the penis curves more than normal.

I’m not seeing “the natural beauty of women” here. I wouldn’t want my teenage daughter thinking “I need to look like that model”. There’s too much pressure on girls to be bizarrely skinny as it as.

One of the reasons why I love to study advertising… I know, this ad from 1950 is not about sex, but it is an important reminder that people in the year 2050 will probably be just as amazed and disgusted when they read ads from today.

Thanks to Copyranter at Buzzfeed for letting us know about Stanford School of Medicine’s incredible gallery of tobacco advertising themes.

Klingons play an important role in the latest Star Treck movie, and Spock sports a Vulcan bulge for Uhura. So how do Klingons, Vulcans and other Star Trek species have sex? Here’s a rundown:

Denobulan Sex: Denobulans practiced polygamy. Each Denobulan had three partners, and each of these had two other partners. Denobulans were liberal about sex, with sex occurring during Denobulan mating cycles.

Deltan Sex: Deltans were so highly sexed that they were forbidden from having sex while in Starfleet. Deltan sex was such an intense activity that a member of another species who had sex with a Deltan could go insane as a result.

Vulcan Sex: Vulcans were ruled by strict logic except every seven years during pon farr, which was the Vulcan mating cycle when a Vulcan lost all emotional control.

Klingon Sex: There is not a single thing about Klingon sex that could ever be described as “gentle.”

Ferengi Sex: The Ferengi were the from the planet Ferenginar. They had prominent ears which were also their main erogenous zones. Foreplay for Frengi was called “omax” which is the stroking or massaging of the Frengi ear lobes. To call male Ferengi chauvinistic pigs is to be kind. Female Ferengi’s didn’t have life so good—they were forbidden by law to wear clothes and had few if any rights. From the official (and unofficial) Ferengi Rules of Acquisition:

#21:  Never place friendship above profit.
#31:  Never make fun of a Ferengi’s mother. Insult something he cares about instead.
#40:  She can touch your lobes but never your latinum (money).
#76:  Every once in a while, declare peace. It confuses the hell out of your enemies.
#111:  Treat people in your debt like family … exploit them.
#139:  Wives serve, brothers inherit.
#255:  A Wife is a luxury… A smart accountant is a necessity.

Andorian Sex: A blue species of tall, slender people from Andoria in the Alpha Quadrant. Andorians had four genders as opposed to the usual ”male” and “female” of other species. They had antennas on their heads which were imporant devices for communication. The reproductive organs of the Andorians remained retracted until they reached their firstpuberty at age 12 or so. As a result, Androians were raised in a gender-neurtral environment. Andorians “kissed” by touching the tips of their antennae together. Their sexuality appeared to be quite complex.

And yes, viewers still wonder if Garak and Bashir were gay.
