(NSFW) Is it a universally common thing for boys to measure their johnsons?

A while ago I was talking to my friends and the subject popped up on penises. Some guy casually mentioned about when he measured his as a boy. Another guy friend then chimed in about it. This was the first time I ever ran into anything about this being a “guy thing” that all guys supposedly do as a boy.

When I said I never measured mine as a kid they just called me a liar, even this girl we were with. She was like, “You’re just lying. Every boy measures his dick when he’s little.” And whenever I get into situations like this, I get fiercely frustrated because I wanted to be like, “NO BITCH – I seriously have never fucking measured my dick. Don’t assume everyone does the same fucking thing.”

Now tell me what this whole thing is about. Is this just my friend group being the silly people they are or does every guy more or less do this when they’re young? I’m curious now.
