I don't think so because I haven't seen all the big dicks there are in the world, just have seen the biggest dicks shown in porn.
But I can see my dick is as big as the biggest dick seen in porn (Mandingo, Jack Napier, Mr. 18...).
And of course, not all men with big dicks are in porn.
Apologies for resurrecting an old thread, but it turned up in a search. I've also not read all of it, so this point may already be covered.

Mate, you are kidding yourself if you think that Lex Steele and Mandingo are 7" and 8" respectively and that your dick is the same size as theirs or even bigger. In those comparison photos you posted you are clearly pressing your bottom hand into your pubic area and your top hand is right up against your bottom hand, and you look like you are trying your hardest to get every last millimieter of length out. Mandingo, however, is relaxed, it doesn't look forced and there are clear gaps between his bottom hand and his pubis and between his top hand and the bottom one. Those factors alone could easily account for 1.5" - 2" difference.
You and others need to be realistic - video or photograph yourself f*cking from any conceivable angle and your dick will never look like Mandingo's, and the reason for that is not trick photography or midget co-stars, it is simply that his cock is bigger than yours. I know this because I am 8" and I've seen myself on film many times, and whilst I've thought "Blimey, that looks pretty impressive!" or realised that I am actually similar in size to the Rocco Siffredis and Peter Norths of this world, it is not up there with the true "giants". I'm ok with that though, because my size at EQ 10 is already pretty much at the limit of what my gf can take (and we are talking here about a woman who is into big cocks and who gets turned on by pain).
I do agree with you though, that these stars are nothing like the sizes claimed. Mandingo, for example is more like 9.5" - 10", rather than the 12" or 14" claimed. That in itself shows something, ie: that few people, male or female have any real idea just how absolutely f*cking enormous and RARE a 10" dick really is, which casts serious doubt on all of these "my ex bf/my gf's ex (delete as applicable) was 11" stories one sees on here and other forums.
Im not trying to run you down at all. I'm merely trying to correct what I see as an unintentionally false claim. The reality is that you have a big dick, probably in the top 5% or so, but it is nothing exceptional or freaky like the above mentioned porn stars.
