Your nervous system has finite bandwidth. The extra movement and sensation signals drown out the "need to pee" signal, making it seem less urgent. It's also why we rub the area around minor injuries to relieve pain.
It is a theory to explain how genie knows about things like automobiles and 20th century movie stars. It posits that these are only anachronisms if the story is set in the past, as commonly assumed. But setting it in the far distant future eliminates the problem. It also explains the apparent "magic" in the world as remnants of a fallen high-tech civilization.
Rajah the tiger? Genetic engineered. Magic carpet? Hover tech. Buried stop signs (video game only)? Ancient relic. It's really quite surprising how well this theory fits.
I would really like to know how they measured this. I get the feeling that the men being studied didn't come out and state, "yes, I have a greater intent to rape" on a survey or something. The researchers must have been using something as a proxy for "intent to rape".
I'd also like to see the stats for how many of the men have actually raped someone. For example, if 86% are rated as "more likely to rape" after watching porn, but 99.9% don't rape anyone, then that would suggest there is no correlation between porn and rape.
