For example, you linked this page from the question about masturbation; the problem is, it doesn't answer the question at all. Masturbation does not cause anybody else material harm. Your answer only shows how stealing, lying, not paying taxes, and causing an unpleasant smell are wrong (though I still don't see why the diapers is really wrong or a sin, just socially unacceptable).

Is there a better answer for why other natural impulses and desires that do not harm or even affect other people are wrong? Thank you.

The rabbi does not get into why certain things are forbidden by the Torah. He is simply challenging the notion that BECAUSE it is natural it MUST be okay. Hence his examples of natural things that are not okay. You are right--this does not mean that all natural things are bad. It does not explain why masturbation, for example, is wrong. He is only addressing the sentiment that all natural things are neccesarily healthy and conducive to goodness and a better world.

i think this notion of "natural equals good" is one that pervades the cultural left and i'm glad the rabbi addressed it.

All the best,

Animals cry to clean their eyes. Human beings are unique in that they cry for other reasons - for ex., when one is sad. And for human beings to reach orgasm, one requires mental sexual excitation.

The sexual act is supposed to be a 2-person deal, like hugging, a mutual sharing. M., on the other hand, requires a form of mental (int. and emotional) treatment of the opposite sex as an object, or what Buber would an It, and not a Thou. Often M. involves looking at pornography, but even without physical pictures, we can assume it requires fantasizing.

M.is in the same category of sins that good people can commit as neglecting to say good morning to the doorman, or thanking the barber. To forget that an entire class (gender, economic, et al) of people are not thinking, feeling souls hurts you, women, & everyone!
