Alright, as a penis connoisseur let me explain why makes "the perfect penis". The above is a very good example, it being practically perfect.
1. It MUST be straight. It cannot be curved in any way.
2. It must have good thickness to it, without being grotesque, otherwise known as "girth".
3. It must be a good length (long) but it mustn't be too long as to be out of proportion with the girth. Skinny dicks made so by the length or giant heads with pencil dicks aren't hot. You need the magic ratio of length over girth.
4. It must be what I call "aesthetically pleasing". What I mean by this is that it must be relatively uniform in color without any blemishes or discolorations. It must not be too veiny. Some veins are alright but overall you want it to be relatively smooth.
5. It must at least stand out 90 degrees from the floor without "drooping" when hard. Even better, it must stand up (as above) when fully hard. This is the hottest position and signals the man is a true testosterone factory.
6. Finally, it needs a garden on which to grow. There needs to be a good amount of pubic hair to tastefully cover the base. Bald dicks are a turnoff, but dicks lost in a forest of overgrown hair is a turnoff too. You need to strike the right balance. (Above is good, but I would have a bit more).
Now you too can pick out the perfect dicks for yourself! You are welcome.
