Help - Serious answers only please

Since I was 14 years old I always wondered what my problem was, but never went to see a doctor because I was embarassed. I am 21 yrs old, 6'3 and 200 lbs. I have a serious problem with my penis size, errect it is only 2-3 inches, and i have seen NO width increase all the way through puberty. I have been researching several different things and I have ruled out micropenis because of the reading I have done. I am wondering if I have some sort of testosterone problem, but I grow facial hair, I have grown taller, i show no other signs of not going through puberty. I do not understand what is going on, and was wondering if anyone would be willing to lend their opinion.

hi, since you have gone through puberty and have noticed no significant development then i feel it would be worth seeing your doctor. they will be able to test your various hormone levels and if necessary refer you on to a specialist, although you may feel embarassed about it they will have no problems with it and will do their best to put you at ease. this must be worrying you for you to write in and the last thing you want is to be fretting about this when a visit to the doctor could answer some questions. hope this helps.
