Here we go again . I ' ve already explained this . Your argument is flawed because it makes inappropriate assumptions . Premise Masturbation is not mentioned anywhere in scripture . Conclusion Masturbation is not a sin . That ' s a pretty solid argument , but let ' s explore some of your statements next . Lust is the desire for that which is forbidden . And why are you bringing up pornography in an argument which does not call for it ? It sounds like your mental image of what is going on has more than a few cultural assumptions . Let ' s refrain from that and not make blanket statements like masturbation is sin when it is not . Example I can say that driving is illegal because some people drive drunk . It ' s an improper argument , and the focus should be on the actual sin , rather than the vehicle of some people ' s sin .
