There was a serious point behind my joke of posting the Taylor cartoon (and I hope you at least saw some humor in it), namely that there is no limit to men's wishing and fantasizing about having a bigger dick, and that for almost every dick on earth there is another dick that makes it look small. On this site you can find many, many threads discussing what "average" penis size is and how many men today, because of the influence of modern video pornography, have badly distorted ideas of statistical norms and of their size in comparison with those norms. On the other hand, a person who has such distorted ideas (which you may have) will also find material here to confirm them, since this is a site about large penises.
From what I know (much of which I have learned from reading threads on this site and following links to reports on studies of penis size), and from my judgment of your photos, your penis measurements would go squarely in the middle of any statistical graph. I'm not sure if what bothers you is the impression that you are positively small (which you aren't), or if what bothers you is being not big (which is the case). If it's the former, then reading discussions and reports on average penis size may correct your false impression. If it's the latter, then your problem may be more stubborn.
