My hair is the same.. much curlier in front (3a) and wavy in the back (some days it's 2a/b, like today). I've never gotten stares, maybe you're just paranoid? I don't find different curl patterns to be odd, it's very normal. Hair does what it's going to do. Do you have layers? Is it shorter in the back? That's mainly my problem. You could pin a small portion of the front back, and that might help break it up a bit. Try different styles. Also, you might want to try a different hair cut.
