I dont know if it is always a bi-product of a poor relationship. I had a GF a long time ago and we got along so well together as best friends - 2 peas in a pod. However, when I orally stimuated her to the point of reaching her happy place, she would curl up in a ball as if in shame about feeling so good. Which left me unfulfilled and asking in a funny timid voice... "What about me?"
