Ladies, answer this please...?

Man girls have said I have really great love making skills. I've been described as very "smooth", "suave", etc...they've either told me to my face or told other people, who told me. The frequent call backs afterward, whether they were long flings or would-be one night stands, kind of made it concrete that they were being honest. This is obviously all flattering, but I've recently become self-conscious about my size. It's average by anyones standards, nothing more, nothing less. Although it obviously doesn't impair me from getting women hot, it's still an personal issue for me that I keep private. I guess I fear the possibility of a girl choosing some other guy over me because he's bigger, or a girl considering me "small" because I'm not remarkably big. I'm wondering what the best way to get over it is. Also, I'm curious to the fact whether these girls have discussed my size, and if so, what do you think they'd say? "He's average"? Do they even bring it up if it's just medium?
