It turns out that many of the things we think we know about sex aren’t entirely true. So let’s set the record straight and explore what we do and don’t know about sex and the human body. For today’s show, we’re revisiting one of my favorite conversations of all time, my interview with Dr. Lisa Dawn Hamilton that originally aired back in episode 53. Dr. Hamilton is an associate professor of Psychology at Mount Allison University in Sackville and host of the podcast “Do We Know Things?” Some of the topics we explore include: What do we actually know about the G-spot? Do we know what the average penis size really is? Does peeing after sex actually prevent UTIs? Does pubic hair grooming affect STI risk? Can men have multiple orgasms too?
