I think climate has a lot to do with flaccid hang. Where I live the weather is wet and windy pretty much all year round, only a few degrees of temperature either way separating the seasons. Potentially I have a pretty good flaccid when judged by it’s appearance in the locker room after a shower. But at the moment the weather is awful and my flaccid dick looks pathetic most of the time. A good friend of mine lives in Australia where it is hot most of the year and he’s wearing baggy shorts with no underpants all the time and experiencing great flaccid hang. His stats are similar to mine and when we trained together in Ireland I can say that his locker room flaccid was also very similar to my own.
