I really doubt he would be able to drop the habit either way. Most of us who are into this have it so deeply rooted in our psyche, to deny it means living a life in fear of satiating your true desires, inhibiting your own actions and essentially living a lie. Be true to yourself as long as its respectable of others existences.....ohm mani padme ohm, I am the Lotus
And I've already mentioned how supressing desire is a lot like supressing anger. It may just keep building and building until it explodes in a rather unpleasant display. We all remember Terri Disisto don't we? Plus psychiatrists have already proven that trying to deny key aspects of your personality and true nature such as this can lead to psychological inbalances.
So it quite literally really is healthier to just be true to yourself...
Come on man! There are so many worse things you could be into....ever see paraplegic midget porn? ROFLMAO! WE GOT OFF LUCKY PAL!!
