hi im 18 years old and i have a problem regarding my penis and testicles growth. my penis and testicles is still same size when i was at least 12 years old, i know for a fact that i've hit the puberty already i'm 5'9 and my voice is deep. my penis when erect is 3.5'' inch and only 1.5'' girth i have a girlfriend and we've been together for almost 2 months now and all we do is make out most of the time she wants us to have sex but i'm too embarassed to tell her that my package is small. i need help, do i need to consult a doctor because i feel like my testicles is like a testicle for a 12 years old boy.
