SexGeeks: Pheromones, Risky Behavior, and Vaginal Depth

Here's the latest installment (1hr 3mins, 29.5MB).

Here are all the links to things we talked about.

Rob mentioned an interesting study that was conducted in 1996 relating partner selection to immune systems that seems to have at least a mild effect on humans.


Rob talked about a study done on a high school that ultimately produced some cool maps on the sex links between people attending the school. Rob commented on how there were fewer bisexual and gay relationships reported than one might expect.


Rob also talked about an article that indicates a treatment for helping
post-menopausal women to have "normal" sex drives seems on the horizon (a testosterone spray), but that it's initial uses may go towards bringing young women with low sex drives because of low testosterone levels, back up to "normal".


Rob mentioned in passing a Wired article that indicates that a female equivalent of Viagra may be more difficult to create.


We talked about an op-ed piece in the New York Times discussing how
the focus on children in the US interferes with the sex lives of parents.

Lindsay brought up another New York Times article that discusses the rise of risky sex behavior, a new strain of HIV, and how it is
becoming increasingly difficult to target those engaging in risky behavior.

Lindsay mentioned the Seattle Erotic Art Festival, running from April
15th to the 17th in Seattle, Washington.


Rob wondered about men's obsession with penis length, and decided to
do a quick search to see what the average vaginal depth was. It turns
out that it is between 3 inches and 5.5 inches (the latter when
aroused), so the fact that the average man's penis is between 5 and 6
inches, it would seem, should mean that most men should feel
comfortable about being sufficient for most women. Lindsay pointed
out that obsession with length is really focusing on the wrong aspect
of sex. A good partner will overcome any perceived shortcomings of
his apparatus. While on the topic, Rob looked up the average
circumference of a man's penis and found that it's about 5 inches.

Rob found the information about vaginal depth in a strange place, on a transexual site discussion sexual reassignment surgery, where it appears that men considering becoming women suffer from some of the
same issues that unmodified men do, wanting deeper vaginal cavities much the way some men want bigger penises.


We've started a del.icio.us account for bookmarking things we are thinking of talking about on the show as we run across them. If you'd like to see what we're reading, you can check out the list at

We talked about the idea that for single women who choose have sex,
that their married counterparts may feel that coming down with an STD
may serve them right.
