Thanks for your question! Studies have show that the average adult penis size is between 5 and 6 inches when fully erect, as measured from the lowest portion of the stomach; just above the base of the penis, to the tip of the penis. It’s important to understand that the size of a guy’s penis is determined by genetic traits that he inherits from his parents̶̶̶ just like your height, eye color, and skin tone. Most guys are fully developed between the ages of 18-21 so the size of your penis is completely normal.
- Penis Size
- I am 16 and have gotten a deeper voice, have pubic hair, and armpit hair. However I have had no growth in the penis, or testicles. Is this normal or should I seek help?
- I’m 15 and have shown all signs of puberty like body hair and a deepened voice. But my penis still hasn’t grown, or at least it doesn’t look like it has. Is there still hope or should I seek medical help?
- I’ve accidentally seen my friends penis and it made me start wondering if mine is too small. My penis is 3 inches flaccid and around 4 inches erect. My friends talk about how their penis is 6-7 inches flaccid and I was wondering if my penis is too small or if it will grow to a normal size. I am also late to grow in height and get hair and have a deeper voice.
