hmm I wouldn't get it buzzed not a lot of girls like guys with buzzed hair haha :) but I would recommend you get your hair cut short but not buzzed like this or if you want some kind of an edgy look you could go with this one: and you can always ask what your hairstylest thinks they know best because they are experts in hair and you deff. do not have a big forehead I think you are just paranoid about it.
Yes definitely cut it short. Long on top and short on sides gelled over. ex. https://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&docid=4iCT32xjyOfUeM&tbnid=AXG_LefxH-NHTM:&ved=0CAUQjRw&url=http%3A%2F%2Flitejiaju.com%2Fnew-mens-hairstyles%2Fnew-mens-hairstyles-10%2F&ei=b1FHU-bZO6L4yQGR1oC4DQ&bvm=bv.64542518,d.aWc&psig=AFQjCNHQo0y23DExiELCZxXPBY2gfWdL_Q&ust=1397269223232073
