It's hardly a distinction without a difference: pedophilia is sexual attraction to a pre-pubescent human. Sexual attraction to young women is normal among men, it's been proven so many times and in so many ways it's beyond dispute. It's the shape. The dingus meter does not lie, nor the respiration rate, nor the heart beat nor the entire body of human history and literature. Character, morality, practicality, goodness and the odor of bubble gum prevent most from acting.

As for the watering down of the word "rape" to mean just about anything, that's may be on the legal community, but the legal community has certainly been influenced by the feminist rhetoric.
