It doesnt matter at all! For example, if you meet some girl on the street you will know how tall is she, but if you meet a girl on internet, and at first you dont know her size, but at the end its not that bid deal. Because one time i met a girl on a dating service and she sounded nice, but when we actually met in live she was huge, but i dont care, i liked her a lot. We were together for years. So there you go, if you dont judge by the size you can be with every girl, of course if you like her.
