How do most circumcised men not realize their penis is numb?

It just blows my mind that circumcised men don't realize something is very wrong with their penis. Don't they think it's odd their penis is numb and pleasureless? Do circumcised men even feel anything from a blowjob? Is a handjob even comfortable? I know it was done as a baby for most but how does it not eventually occur to them? Is it denial?

I'm just trying to understand the mentality of circumcised men and why they aren't waking up to the damage done to them. I guess another question is how did everyone here wake up to circumcision being mutilation?
