There's no "exact" or "proper" penis size at 17. Usually our penises are fully grown at this later stage of puberty; however, late on-set puberty could mean your penis could still be developing. The average fully erect penis for adults is around 5.5 - 6.0 inches in length. Flaccid penis size varies greatlyfrom very small (which tend to be "growers") or could be very large in the flaccid state (called a "Show-er"). If your erect penis is anywhere in the range of 5-6.5 inches, your penis size will be among 90% of other guys having penis sizes in the same range as you. Only around 5% of other guys will have penises larger than your erect penis. Rest assured that you will likely never have a girl think your penis is in any way 'small' if you have a penis size in the median range; likely she will even think your penis is large & be quite excited and very horny to take it!
i would say about 6.5
well the size of the average mans erect penis is 5.5- so for a boy of 13 years it is pretty big.
Not really, the average full grown penis is 5'' to 7" so you are average but not big.
No, that is actually 2.5 inches above average. Consider yourself big.
The fact that a big penis is in his room. relevants the fact tat he is orny
Not for you, it is perfectly normal. Average for an adult is 6 to 7. If you are this big already you will have no problem in the locker room. You are measuring the top side aren't you?
It's about average. An average penis is 6 1/2 inches. No, dont worry it'll get bigger when you get older 7'' is quite small
The average size of the human heart is as big as your fist.
Because my penis is big.
Probably as big as any other mans testicles.
Outside of race, there are no predictors of the size of a mans penis. The only real way to tell would be to check yourself.
Only a few centimeters long.
