Okay, i am 13 year old male and i think i started puberty. I have thin black pubic hair on my tests and on the base of my penis and they are moving up higher everyday. I also have a vein on my left test. which usually some teens and men get when they enter puberty. I also get frequent erections and everything seems to arouse me. My penis isn't really growing though....But the main problem is...If I have entered puberty....I have not really grown at all. I am 4:9 in. Tall....I hate being short and i dont understand why i am not getting a growth spurt...I started puberty a couple months ago....Where is the spurt..? Please help! And did I really start puberty?
