First, I have to emphasize that what I said below is only a possible and probably partial explanation. "Maybe"and "Some but not all" are the keywords, even if I don't spell them out. Let's say, some of (I suspect that it's most of, but I have to be careful) those people who cannot give themselves pleasure (hand jobs) have muscular dystrophy. (From the video Chris provides, the man in the video looks like so. But I can't be sure. Again, I have to be careful.) Muscular dystrophy mostly affects boys. I think you guys got it. I don't have to write anymore. --zpdrmn
