As you two learn the things that really fire your senses and stimulate one another, you will deepen the experience beyond a point where the size of your penis makes any difference whatsoever. The bottom line is that your penis is going to be the size it was destined to be and nothing is going to change that. Any partner that is overly concerned about the size of your penis, is not going to be a good partner for you anyway.
