I have never thought that my cock was anything special. I still don't and probably never will.
You sound a very interesting and honest person, and I would guess that people don't know what they're missing. The trouble is that the 'cock' (and the size of it) can become an obsession for very many people, and I'm not immune from that myself. In many ways it's the raison d'etre of LPSG. It would seem that many well-endowed boys grow up thinking that their dicks are in fact normal or average; only in later teens or early twenties do they discover, from the admiring comments and attention of others, that this is not the case and they have become 'desirable' for this reason. A quick glance at your gallery pics reveals how this can have happened to you. In terms of personality, character, abilities you may be richly endowed, but for many all this will be overshadowed - even eliminated - by another remarkable endowment which will come to 'personalise' you. Which is why I've known some people refer to their big dick (the very thing longed for by most males) as a 'curse'.
What can one say? Other than keep it covered! And try to 'manage' your relationships with skill - though that's probably easier said than done. But the fact that you just don't want to be a 'cock on legs' means you'll win in the end.
