From the Times Magazine:
The participants [in the sex experiment] sat in a brown leatherette La-Z-Boy chair in her small lab at the Center for Addiction and Mental Health, a prestigious psychiatric teaching hospital affiliated with the University of Toronto, where Chivers was a postdoctoral fellow and where I first talked with her about her research a few years ago. The genitals of the volunteers were connected to plethysmographs —for the men, an apparatus that fits over the penis and gauges its swelling; for the women, a little plastic probe that sits in the vagina and, by bouncing light off the vaginal walls, measures genital blood flow. An engorgement of blood spurs a lubricating process called vaginal transudation: the seeping of moisture through the walls. The participants were also given a keypad so that they could rate how aroused they felt.
A lovely, lovely word to form in one’s mouth: transudation.

It’s too bad the U.S. is too hot for Jeebus to even consider funding a study like this.
you horny old man! jesus!
I love how the pictures accompanying articles like this one are always so erotic- they have nothing to do with the study, they just wanted to throw them in there to grab your attention. SEX! SEX! SEX HERE!
Charles, you know we are doing this very same type of research – plethysmographs and all – locally, yes? I’ll shoot you an email on it.
Ooh, ooh, I participated in a research study that used plethysmographs at the UW!
The study was looking at alcohol’s effect on sexual arousal. Sadly, I was in the control (no booze) group, but I did get paid to watch porn.
How come nobody ever asks me if they can strap a tumescometer to my cock and show me porn? Huh?
Lovely word to form, if you’ve got a tumescometer strapped to your tongue?
Oooo, oooo, put my bare butt on a brown leatherette La-Z-Boy and you won’t even need to crank up the video!
Every time the U of T Centre for Addiction and Mental Health pops up in a news story, I cringe a little: I had more than one friend go batshit crazy while I was an undergrad, and I had the opportunity to escort them to this facility. It is good. This hospital knows what they are doing, but it is forbidding.
In other words, I would find it very, very difficult to get an erection within its walls.
