No!
Although some young men are worried that their penis is smaller than everyone else’s, this is unlikely. While there is some difference in size, it’s not as much as you would think. Things like a cold temperature will make your penis shrink, and so will being anxious about stuff. Also, as a rough rule, the larger a penis is when it is soft the less it will grow when it is hard. 90% of men have an erect penis size of 12-19cm.

Getting some perspective – when you look at your penis, if you are standing up or lying down, looking down on it, it will look smaller than it is. Looking in a full length mirror makes it look larger (in reality it will look the size it actually is!) and remember this is how big your penis is to other people.
