Most of the suggestions amount to telling the man with a small penis that he’s just overthinking the whole thing, because sex and relationships and self-worth are about a lot more than penis size. This is of course true; the penis doesn’t make the man.

Absolutely!

But if so much of the culture is telling him that the penis does make the man—that, say, Donald Trump’s fixation on crowd sizes isn’t just run-of-the-mill insecurity but insecurity about his tiny dick—how can you expect him to believe you?

The reason those insults are used is because those shallow people build their entire identity around toxic manufactured symbols of masculinity instead of good measures masculinity are riled up by the comments. Calling into question their penis size represents, to them, the entirety of their shallow version masculinity. Penis size is likely one of the worst measures of masculinity. It does nothing to speak to your character, compassion, strength, knowledge, courage, or trustworthiness. If you’re building your self image of yourself with positive masculine measures, any comments about penis size should be immaterial to you. Why recognize someone else’s judgment of your anatomy as the sole measure of your worth?

Further, I don’t quite understand the anxiety some men have regarding having smaller penises. Where is it occurring that their penises are on display for judgment by members of the sex they are attracted to so often that they are ridiculed for its size so frequently? If it is during consensual sex acts, would you want to participate with someone who would find you unattractive in any way irrespective if its your face, body, or genitalia size or shape?
