When I was sixteen I was sent to a gynaecologist for irregular periods. The specialists in those days didn't require a nurse present so I was very nervous being there. He was an older gentleman in his fifties.
He told me to get undressed and lie down on a table and put my feet in the metal stirrups. He then proceeded to open my vaginal lips with his fingers going in and out, then he rubbed my clitoral area in a circular motion until my breathing became faster and a warm feeling came over me. Then he said that was an orgasm and it would help me relax during his exam. WOW! was I relaxed, I couldn't wait to be alone to duplicate that feeling.
