I used to try my hand at teaching some of my female friends how to give head. I would have to agree with Bronx Bombshell. Most if not all of what she said should be text book if there was such a thing. I had a friend who had a bad experience that gave her a intense gag reflex. She loved head but just couldn't do it because if the emotional damage and psychological damage. So we would have sessions 3 times a week where she would lay her head on my stomach and gently we would spend hours with her sucking and nibbling only to try to go down and come up with no help from me because hands on her head would be a psychologican instigation to more abuse. She ended up, after a lot of interaction, coming back to a place of comfort. It was like her first time all over.
