L is for Lesbian Bed Death

Lesbian bed death” is the term used to describe the steep decline in sexual activity that is thought to occur in long-term lesbian relationships.

For the record, research has found that on average, lesbians do tend to have less frequent sex in long-term relationships than other couples (opposite sex and male same-sex relationships).   However, a decline in frequency of sex occurs in pretty much all types of long-term relationships.

Additionally, it is also found that on average, women in same-sex relationships have LONGER durations of sexual activity (avg. 30-45 mins), compared to other types of couples (avg. 15-30 mins).  And levels of sexual satisfaction in lesbian relationships are just as high on average as in opposite sex, and male same-sex relationships.

So they may fuck less, but when they do get down to it, they really put in the time and effort.

P is for Penile Plethysmograph

A Penile Plethysmograph is used to measure bloodflow to the penis.  Bloodflow to the penis of course indicates sexual arousal.

The two main types of penile plethysmograph:

  1. Volumetric Air Chamber (measures displaced air in the chamber to see how much more space the penis is taking up)
  2. Circumferential Transducer (a ring or strain gauge is placed around the shaft and measures changes in the circumference of the penis)

Plethysmographs have been used widely in research.  Usually participants will be strapped up to a machine and shown various images or video, then the plethysmograph can measure the degree of arousal that each image provokes. 

One of my favourite ever studies using this method found that homophobic men show greater arousal to depictions of gay sex than less/non-homophobic men.
