We've been down this road so many times *sigh*.
Yes people it is possible that people may have posted their pics elsewhere, prior to coming to lpsg! Oh, the horrors, they all must be fakes if they didn't pop their cherry here, right? The complaints are always brought by n00bs and reinforced by the extremely stupid.
Short of evidence, which would be knowing the person in the pics in real life, we are never going to know if anyone on here is who they claim to be. Get over it.
Welcome Lisa, you don't owe anybody jack shit, but I will warn you that this is a pack of dick experts. We know that statistics and you will never get anyone to agree that your man is 12''! Not unless he's measuring from the asshole up. That's a pretty dick alright, nice and thick, but I'd give in (in the numbers based in factual reality, NOT porn) about an 8x6. I'll never understand why guys with huge dicks feel the need to inflate their size.
Look at his hands- his dick simply COULD NOT be 12' unless his hands were about 14" and I doubt there's a human being on earth who could say that.
FWIW, there are probably less than a handful of people in the world with ACTUAL 12" dicks, and I doubt even one of them is currently on this site.
