mirrors in the mouth

I have to be totally honest. Today was not a good day for me. We were asked to use the mirror on one another and find the different anatomical parts of the inner mouth. I was super excited to find these on my partner and even felt pretty comfortable doing it... but when it was my turn to be in the chair, i felt my heart pounding in my chest and i had to refrain from fleeing!! I was scared and even had feelings of irritation. I understand that we are all learning, so i wouldn't have us do anything different.. but i noticed that i need more confidence in my partner and be more specific with her about what she can do to ease into my mouth. I think i also need to be exposed to more than just one partner.. that way i can see more than one mouth and i can feel more comfortable with others in my mouth..
