Statistics might show that taller people have difficulty orgasming, I don't know one way or another. HOWEVER. The idea that this is because of the distance between brain and genitals is patently ridiculous. Think about it in terms of all the other commands that get passed through the nervous system: Are tall people noticeably clumsier? Less coordinated? Less able to perform tasks that demand fine motor coordination? Nah, that's absolute nonsense.
