BRAVO! that's the point....younger guys are too into porn and less into real life. They have to assume the fact that porn is a lie. It is as fake as any other movie. When you see soft cocks in porn, they're often semi, cuz the actor doesn't come to the set with the cock he has from outside. He touches it, he gets aroused (obviously), they use products to enlarge their cocks for the moment (injections, pills etc) AND they are chosen because they are big....because it is more gratifying for a man to see an ideal man, that reminds them of a "hero of masculinity", rather than the guy next door.
The result is, they think that a man should be at least 6 inches when soft etc. Plus, i have to say that when you look at your soft cock from above (normal perception when you look down to it), it obviously looks smaller than it is when you see it frontally. Because you do see the start, but not the full lenght of it.
Being that much into porn and that less into real life and real experiences with their peers, they get messed up and insecure, at the point of feeling a sense of Anxiety for not being able to fulfill their ideal of big cock.
They guys in the pics are mostly average, but i'd say some of them are "big".
And yes, cocks like mine, that look very big when soft, do not grow too much when hard. I know men who look small-average when soft, that get really big cocks when hard....
