I have been with enough males and seen enough penis' to know that a guys body type does not necessarily tell you what his penis will be. A lot of the time it can be a sure sign of what to expect but also you can be either pleasantly or unpleasantly surprise, interested in hearing from men and women about your opinion on this
Generally the smaller the guy the smaller the penis, but heredity enters in too. Some of the guys with the biggest penises were under 6 feet tall.
It is never a sure sign, proportions are reliably unreliable. Any body type/size can be attached to any penis type/size. Don't waste your time trying to figure it out, if you are a attracted to a guy then go for it and enjoy whatever combination you get.
The size of penis a guy has zero to do with what body type they have! Just like it also has nothing to do with the size of feet they have like some seem to believe. As kairilove says above enjoy whatever combination you get.
Jonah Falcon, who has the largest penis in the world, is 5'9". Ron Jeremy, who has a very famous monster cock, is 5'6". Even if you see a man's flaccid penis, it doesn't tell you much about the size of his erection.
