Will my 6 inch penis grow to 7 inch.14 year old that has not finished puberty with little pubic hair

Relax and stop to...: Your current 6-inch penis is long and good, and you still expect another 4-5 years to grow since physical growth comes to halt soon reaching adulthood, for men, roughly age 18, as pre-coded and decided by genetic factors. So, stop worrying about your manifesting secondary sex characteristics, give time & patience, and you will be fine most likely. More? Seek evaluation & counseling.

Probably: Do you anticipate that future sex partners will bring a ruler and measure you? What matters is not the length of your male organ, but the size of your heart and the quality of your character. A crucial part of maturity is learning to order your priorities.
