I think it's possible that some guys don't. I know an asexual guy who doesn't masturbate, doesn't want sex, can't get turned on, etc. And some guys may not believe in doing so but believe in having sex only.
It's probably not as common as it is with women, but I think that yes, some guys just don't masturbate.
