I know that some guys can, and that's fine for them, y'know? I went through intense bouts of shame and guilt over it, when I was an early teen. (Which is why I set the average at twice, daily, because gods know I beat off more than twice daily when I wasn't feeling guilty and abstaining.) I think the longest I went without it, back then was two months. Ever since I was in High School, though, (which would be about fourteen years of age for folks not familiar with the U.S. primary school system) if I go for more than several days to a week without getting off regularly, I start to get really irritable, short-tempered, and more aggressive. I don't like myself much, when I'm like that. About twice per day seems to keep all that at bay.
