I certainly wish they'd included the audio portion of the experiment: "Oh, Dr.Heinriech, I love it when your erectile tissue creates friction with my labia minora." "Oh yes, professor Reinstadt, my penile ducts are pumping. The muscular contractions are getting quite intense. Oh,,,here,,I'm arriving!!!"
Haha, that was great. If a girl ever asks me to talk dirty to her during sex, I'm totally going to start saying shit like that.
