I've been studying the functional morphology of intromittent organs (that is to say, how penises work) since the mid-1990s. I've worked out how the arrangement of collagen fibers inside mammalian erectile tissue stiffens the penis during erection, and described the weird spring-loaded anatomy of the alligator phallus. It's exciting to have the opportunity to work out how mechanical forces might shape sex in cetaceans.
