I feel like in some parts of puberty i excell at and other parts i fail at

im a 17 year old. 6 ft tall 225 pounds in weight. i feel like in some parts of puberty i excell at and other parts i fail at.. i have big feet hairy face hairy belly/chest/armpits semi deep voice. but then i have small hands small wrists very little arm and leg hair.. i also have lot of hair in pubic region but small penis.. im 1-1.5 soft and 4.3-4.5 erect. but its very thin looks like the same penis ive had since 6th grade.. im scared ive seen a doctor about it he did blood tests and said my testosterone lvls were normal. this is a really touchy subject i think about it all the time like will it grow? i have a girlfriend we've been together for a while now she recently moved 800 miles away for school. we still talk 6-8 hours a day and she always talks about marriage and children. i want that so bad but i always think it will never happen because im small. i think she knows.. cus many times she tells me "idc how big it is i love you for you, not your penis size" but still i feel like less of a man. i literally cry myself to sleep sometimes thinking of the shame. i pray constantly ill grow bigger. yeah im that desperate i pray that ill get bigger down there.. when i know theres many other things i could pray about. please someone help me do you think i still have time to grow? should i make another doctor visit with my dr? and ask about hormone treatment? i just want to be normal down there. thank you all.
