I agree with Ginger, just enjoy the journey, and don't feel bad. I remember it took me 1 and 1/2 years of great sex with my boyfriend before I came. I had been able to make myself orgasm since I was like 10, but I had to get to a point where I felt uninhibited enough relax around him. Sometimes it’s hard to share that private part of yourself, especially when you’re young. This is probably more about her and her comfort level. I would just continue to enjoy yourself, and continue to stay attentive to her, and it will happen.
