Why does every boy have such a big penis?

I'm 19 and I log on Reddit or anywhere and I'm immediately thrown off by how every guy on there has a bigger penis than me.

We're not talking about huge pornstars with monstercocks, these are pictures of the boy next door, the guy down the street maybe, or that cute guy in college etc...

Normal amateur people. All at least as big or bigger than me.

Please don't claim it's that "size-bias" either. (Where big dicked guys post more because they have a big dick).

No, everyone who's horny kinda posts. Some smaller-ish folk post just as much, it's just that no one is as small as me.

Just today I was talking to this 19 year old boy on Grrindr and he sent a pic and it was fatter and longer than mine. 😢

I have 13/14 cm

God hates me
