i'm 25 years old

i'm 25 years old, 5'6", 135 pounds, poor skin, and very lean.  So you would think i was in ok health, but i look as if i was in 9th grade.  i have very little hair under my arms and have facial hair only on my chin and around my mouth.  I havn't shaved my cheeks in my life because i've never had to.  when i was in 10th grade i was shot with hgh but only 4 shots of it, it allowed me to start growing but i still look young and its hard to get laid when i look as young as i do.  the only girls that hit on me are the 16 and 17 year olds at the gym and I'm not that guy so any ideas whats wrong with me.  yes i have pubic hair and i can *** but i want a beard and i want my face to look like my age.

Some men just naturally look young. But, it would'nt hurt to see your Dr and have your hormone levels checked.
