Your doctor sounds lovely!
Are you still feeling concerned? In your first post, it sounds as though you wonder if your confidence is crushed, it may affect your ability to cope with pain? I remember having similar fears before my first birth. On the one hand, I wanted to be positive, because I didn't want to scare myself into pain. On the other hand, I didn't want to be unrealistic and then unprepared by pain. It was very confusing!
Birth does hurt for most women, but humans are adaptable and we have so many ways to rise to the occasion. It's a balance we learn to walk as parents - learning where we have our power and where we have our surrender.
I no longer put very much stock in anyone who says you just have to not be fearful and then you won't experience pain. Fear and pain are very important signals from the body, and their purpose is to help keep us safe and to help us nurture ourselves. These signals help us tune into what is important to us, and where our needs and boundaries are. What I have found more useful when encountering fear and pain is to be very honest with myself, to reach out to people around me, and to try to find a way to breathe into that fear, or that pain, without judgment, without trying to force it away, without trying to cling to it. Sometimes then, we know as best as we can in that moment, "Now I need anesthetic relief," or "Now I need to get up and move." Or, "Something isn't right, I need help." Or, "I can do this, I got this." "Someone tell me what I need to do. I trust you." "I know what I need to do. I trust myself." Sometimes we just know we are hopeless and helpless and that is ok, because we are human.
In your later post, you describe going through some very intense pain as a child and the way that has affected you. Do you have a plan for dealing with your triggers (IVs?) - so that in the event you needed one, you can have maximum control and sense of safety in the situation?
