Dear Emuniyahu,
I'd rather not get into the rightness or wrongness of the approach of that Rov. What would be my place in such a serious Torah discussion? What I will say is this: I feel that the truth about yourself - the very real person you refer to here (for some reason) with a stagename - is far more relevant than this Rav's spak, opinion, or whatever people want to call it.
Please lose the shame and feel free to describe exactly how often you have been looking at porn, how often you have been having sex with yourself, what kind of porn or fantasies you typically choose to use, and what other sexual behaviors you engage in that you see you have been failing at...in other words, what really brought you here?
What brought me to go to meet with other recovering people for help was that my habit of porn use, sex-with-self, cruising watching women, phone sex, dirty books and movies, and meeting women for sex-related services (though not sex), was a process that slowly grew over a period of fifteen years. Marriage made it all much worse (contrary to the advice of a well-meaning rov), asking my wife to be more sexual with me (advice of another well-meaning rov) made it even worse, fighting it and struggling in near-total secrecy drew me further into self-lying and spiritual isolation, and I got worse and worse. It started with just a little porn use, not masturbation...just to let the pressure off from the bitter struggle. I knew that when I finally "gave in" and had sex with myself (you call that "masturbation") I could again think clearly and reach for Hashem wholeheartedly...it felt like I was doing OK again! But of course that would always just make it harder to say no the next time, and upped the anty to make me need more the next time.
What i am saying is: how about talking/writing about yourself from now on, instead of about "the Torah". You - and all of us - will get much, much further that way. And also, no feelings will be hurt! For our weakness is a davar hashoveh l'chol nefesh, here.
Love,
Dov
