Episode 2: B is for Butt Stuff Why do straight women engage in anal intercourse?
CORRECTION: At the end of the video, Rob and Angel (1:31:00) answer a listener question about anal fluids and risk. Rob says that anal sex is 400x riskier than vaginal sex for HIV transmission, but said he thought he was misremembering that statistic. So, we looked it up. He was misremembering. According to a Canadian AIDS Treatment Information Exchange (CATIE) review of several HIV meta-analyses, risk of HIV transmission is up to 18x higher from receptive anal sex than from receptive vaginal sex.

Where did that first, high number come from?
Studies have shown that viral loads are up to 500% higher in rectal secretions (the mucous membrane fluid near the rectum) than in blood and up to 2500% higher than in semen!
