Hi there, I am 18, and don t think ive reached puberty. My voice hasn t broken, I don t have any facial hair or any armpit hair. my penis is about 4in erect, but since the age of 15 ive had a small about of pubic hair about an inch high above my penis. Im 5ft 7, and 18 stone. I also have a twin brother, who s the same weight/height, and he is the same. for the last 2 years I have been very depressed, extremely moody with no motivation and just havn t felt right, always full of anger, and am starting to worry about my hormal balances etc. will I ever develop? I m really worried and upset, and have no confidence now in anything I do. Thanks, Joe
