interesting observation.

i've often been struck by the widely reported observation that murderers and rapists typically feel more guilt about masturbating than they do about their crimes.

..similarly, teenage boys are the least likely of any population to admit to or discuss their own masturbatory habits, and the most condemning of the practice in others, despite the fact that they are typically the most prolific masturbators of anyone.

i think this reflects the difficulty with drawing ethical inferences from unsupported assertions.
