I'm 16 years old. my penis is 5 inches long when bone pressed and 4.7 inches thick. is it small?

Normal. Your penis is normal sized and will do all that you want it to do for your and your partner's pleasure. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!

Average penile size.
