I can't weigh in on being a dr. however I have driven a car and flown a plane both are very complicated to learn. sex however is not so complicated.

My point EXACTLY :-) If you can learn the proper way to drive a car or pilot a plane with the proper education, guidance, and precautions, then learning to do the same for sexual activity is not the extraordinarily complicated matter that our cultural beliefs make it out to be. Please note that there are many states where an adolescent is legally allowed to learn to drive and acquire their driver's license before they are allowed to consent to sexual activity with an adult! This makes it strongly clear how much moralism and beliefs take the place of common sense and scientific validity.
