Well, you need a small penis to understand it. Most like myself only become proud of their smaller cocks later in life. In my younger years, it brought me a lot of emotional pain, embarrasement, humiliation, anguish, anxiety, depression, self loathing, rejection, introversion etc. on top of not being able to lose my virginity until 22yo because of it, add on top of that needing to masturbate excessively up to 4-5 times a day everyday, just to tame my need to cum from living a constant sexless life. You also over time, sexualise those above emotions, thus rewire your brain and they help intensify your orgasms even more.
So after all the cheating wives, lying girlfiends etc. you get a little older, reconcile those issues and begin to accept these are the cards you're dealt. Not the ones you wanted but you have no choice. You also discover there is a whole community of men who are in the same boat (I read in a condom article 10-15% of men have small penises) that have suffered in the same or similar ways, so you also become part of a tribe and at least you belong to a group with others, not alone like I thought I was before the internet.
These days you can chat about it on forums like this, share your experiences, understand each others pain and of course, show others your tiny cock. Even though its brings women very little pleasure, mine still works fine and I still addictively masturbate every single day, if not more, so it still brings me a lot of joy and pleasure, just like it has since my early teens over 40 years ago.
