Don't sweat it honey, he will get over it. If he really does love you he shouldn't even notice. I have very small boobs and it really bothered me for a long time, and I was afraid my man didn't like them. Then one day I realized boobs are not what make you who you are, and if he couldn't deal with the fact that he didn't have much to work with than he's not worth keeping around.
After I started feeling more confident about myself, I began to make jokes about my small titties.
