Sex and Attention

What you think about during sex matters. A guy who doesn’t want to, ahem, proceed too quickly will think of baseball or something non-sex related. A girl who wants to proceed more quickly might focus on surrounding milieu of a loving environment. These are stereotypes, I know, but the fact that we have them does…

Teens Not Engaging In More Sex

I was struck by this post over at the Well blog. In spite of media attention, teens are not engaging in more sex: The news is troubling, but it’s also misleading. While some young people are clearly engaging in risky sexual behavior, a vast majority are not. The reality is that in many ways, today’s…

Really? This is just a little creepy. A non-for-profit will help you tell your one-night-stand that you may have exposed him or her with an STI via an e-card: Steve, a health care worker in his 30s, had been told more than once that he had been exposed to a sexually transmitted infection. So when…

Quiet Bison get more play

Ha! I knew it. The quiet animals get more play than the loud obnoxious ones: During bison mating season, the quietest bulls score the most mates and sire the most offspring while studs with the loudest bellows see the least action, according to a surprising new study by researchers at University of California, Davis, and…

Yet another piece of evidence for the futility of abstinence education. Masters et al., publishing in the journal Perspectives on Sexual and Reproductive Health, show that an adolescent’s attitude about sex is a much stronger indicator that they will actually have it than their attitudes about abstinence. The study followed around 300 teenagers from Seattle…

OK, so that title is a bit glib, but that is definitely how the press is going to spin this story about birds who have stable female-female mating pairs: Almost a third of Laysan albatross nests in the Oahu colony have two mommies. That’s the surprise in Lindsay Young’s genetic analysis of breeding pairs on…

Farris et al. have a paper coming out in Psychological Science about how men tend to misperceive sexual interest in women. I get the sense that this is a big problem for many women. Any woman who has spent more than 30 seconds in a bar has had at least one random yo-yo hit on…

Did T. Rex have a phallus?

Evolutionary biologist Olivia Judson imagines that they may have. As she writes, there are scant signals cluing us in to the sexual life of the male T. Rex. Did he have a penis? Or perhaps just a cloaca, which avians, amphibians, and reptiles use to excrete waste, semen, or eggs (should he actually be a…

A post on kissing by fellow SciBling Sheril caught my eye, and I figured, why not pick a friendly argument as my inaugural post at Pure Pedantry (sorry, Jake). She pointed out a recent SciAm writeup summarizing work by a team of kiss-intrigued researchers, including psychologist Gordon Gallup, PhD, of SUNY, and quips: “You see,…

This question came down the pipeline from the SEED overlords: Why don’t they make a birth control pill for men? The short answer is that they do make various methods of contraception for men, but most of the more effective ones are surgical rather than pharmacological. Also, given the early difficulties in making a pill…
