what determine flacid penis size?

[curious Al]

Just a general question, but what does?
I know temperature does, but does anything else?
My size goes up and down in same temperature/environments etc. But was just curious!? :P

It's also how you are aroused and what you are thinking or watching can make your penis go up and down quick.

As you have noticed the length and girth of your penis can vary in a flaccid state depending on environmental factors. Some men are larger when flaccid than others. Men who have a very long erect penis (more than 19 cm for example) will usually have a larger flaccid penis. Men who have a very short erect penis ( less than 13 cm, let's say) will usually have a short flaccid penis. On the other hand there are some men who have a 15 cm soft off and only gain a cm or so with a hard on.
If you are concerned about how you look in the locker room I suggest you accept your flaccid penis and work on your abs.
