16 y.o, my penis is approximately 4.92 inches when erect and 1.85 inches flaccid. is this normal for my age and for males? or is this the size of a babys penis? has that size grown or is it still the size of a babys i want to know if puberty worked?

Penile length is measured from pubic ramus to the tip of the glans while traction is applied. Average stretched penile length for boy at full puberty ranges from 3.66 to 6.5 inches.

Self measurement of the penis is often inaccurate. Theses dimensions are small-normal. You are still young and will grow. If you have normal erections then wait for a year or so and if still worried pl see a URologist
