Looks like textbook balding. U are not developing a mature hairline, they are just missing their temples abit so that their hair line is not a straight line down their forehead. You however are receding from the center of your forehead right down to ur temples, the classic V shape. You can see that ur hair is thinning down that line on every spot aswell. Do not hesitate with that bs mature hairline crap, if you want to have hair four years down the line, jump on finasteride. Go see a derm, force him to prescribe you it if he will not want to, and thank me one year from now. Good luck mate.
