Just being really sweet and nice and talking to us and taking an interest in what we do. Also being in good shape and trying to look as beautiful as possible always helps.
Actually rereading what I typed that's basically what any girl can do to get any guy to like her. Really if your like what I described above race may not matter at all. I guess that's how I am anyways, of course some guys may just not be attracted to black girls which may be hard to change.
