Alright I am 16 and I am turning 17 in 2months and and I going into my senior year and my body seems matured (deep voice, pubes) stuff like that but my penis is 5inchs when erect and I am wondering when is it going to grow this kills my selfesteem cause I am alway so close to getting it in with girls at parties but I don't wanna show them my penis cause I don't wanna get embarresed and such but if someone could give me an estimate of when it will fully grow it would mean a lot. Btw I weight 135 and I am 6'1 so yeah pls someone get back to me.
