Without an absolute moral truth how can you conclude what is moral and what is not? In other word’s, how would you ever know that a line is crooked if you never saw a straight line? God is the absolute moral Truth. Anything less is only relative to whatever is it that one would believe is morally sound.
So, since you have not yet come to know God and his purpose for our gift of sexuality you will not see masturbation as morally offensive. How could you since you are basing your conclusion on mere human ideas? You say that you believe in many things and that Christianity is not one of them. So, without God, basically you merely believe in yourself and whatever manifestations your beliefs may have. Therefore, if you justify the “fact” that masturbation is morally acceptable to what would you contrast the belief? How would you contest it since it is derived from you alone?
