I had been VERY impatient for my facial hair to come in. Id felt this way for the majority of my time after puberty. Im improving on how I feel though :p
Because, while there are teenagers with much more hair than me, there are also adult men who cant grow any either. I know in time things will improve, its different for everyone.
Some guys get good facial hair in less than a year on T.
Im just over 2 years on T (And Im only 20years old) and only in the past couple months has my chin stubble developed. Upper lip hair started first, but it has never thickened and become actual "stubbly facial hair", but it creates a shadow. Theres nothing on my cheeks, chin or sideburns. (I dont count peach fuzz).My chin is the only facial hair I get at the moment,) which I have to shave twice a week. I feel so proud of it :p
All we have to do is patiently let T do its wonderful work!
