We still don't have all of the answers on the exact role of all components at the molecular level but we have progressed light years from Aristotle, who stated that three branches of nerves carry spirit and energy to the penis and that an erection is produced by the inflow of air.' The natural erection is the result of an extraordinarily complex process that mankind understands better after the last thirty years of scientific research. Actually, they're not all myths, but we'll get to that. I pass along some of the jokes and quotes I've heard, and I also talk some about the common misconceptions and myths we've heard all our lives about sex in general and the penis in specific.
