Man! I am tired of these adolescence years.  I get no respect from my parents.

I hate going through puberty.  It starts around 12 for boys. I am 14. 
Puberty was not a fun tiime for me, growing my sexual reproduction organs, feeling awkward as my body matures, not a fun time
Facial hair has started to appear for me.  It typically appears in males around 14 to 17 years old.
That is true for me, even now I can barely grow mine and i am twenty one. I still cannot grow a real beard which is not fun, it is an in between phase
