I have come very close to finding my cock twin ... Random question: what's your opinion on the EVERLAST underwear that you're sporting in your pic? I'm thinkin of buying some!
I have seen two dicks here that seemed to me to resemble mine in some degree (though they don't resemble each other): JohnMoore's and SirNeal8's -- though JohnMoore's is uncircumcised and SirNeal8 no longer has the photo in which I saw the resemblance. I once started a thread on this very same topic: http://www.lpsg.org/61106-have-you-got-dick-twin.html
They are great undies, they are quite short tho and sometimes my dick-head or balls kinda hang out the bottom...not such a bad thing always but could be akward for some.
Great question! I've never seen a pure twin of my cock. I've seen one or two that were very similar, and it was kind of a trip!
