Too many doctors want to treat sex as if it were an instinctive function like digesting lunch. It’s not. No one has to teach the gastrointestinal system when to squirt its digestive juices or how to process the potatoes just swallowed. Sex, on the other hand, can be a fumbling, painful, embarrassing episode that can improve with practice and instruction. Moving from successful intercourse to pleasurable sex is not an instinct, but depends on multiple factors, none of which are solved by pushing women to adhere to medical norms.
