Hello, I am 12, nearing 13 and I still don't have any Armpit hair, I have plenty of pubic hairs around my penis, but my armpits have nothing, should I be Worried? My penis is perfectly fine, 4.5", still not cumming. :( my voice is starting to break but anyway, should I be Worried about my armpits?
No, there is no need to worry. Armpit hair often comes later, sometimes much later - 15 or even 16.
Don't compare yourself to others, we all develop differently and at different rates/times.
Hope it helps.
Puberty is progressive and the armpit hair will come in later.
