Masturbation: Does it break the 3rd precept?

According to this answer, it seems like masturbation is not considered sexual misconduct or breaking the third precept. However, the whole point (in general) of keeping the precept is to make good kamma both in mind and body. Masturbation alters the mind state and creates bad mind-made kamma. So ideally, shouldn't it also be considered as sexual misconduct and breaking the third precept?
