Sorry this is such an arichus:
As far as indulgence goes, let me just share this with you, be"H.
Hashem tells us he wants us to practice sexual abstinence with our wives (and it goes the other way, too, for her, of course). Right? This is niddah. About two weeks of sexual abstinence every single month. Teaches self-control, right?
Wrong.
And he knows it.
It does not teach self control, and here is why:
The kiruv and hashkofah sforim kim'at all say that kashrus, niddah, bris milah (RMb"M) and shaatnez, all teach self-control to yidden. Other mitzvos as well, teach subservience to His Will for us in taking many actions that have chisaron kis, difficulties, etc. I am not speaking for all Yidden, here, but:
Plenty frum men are chain smokers, yet do not smoke for twenty-five+ hours every week, on Shabbos. They can go for a whole day without dropping dead, but they still kill themselves, coughing at night, knowing they are eventually going to get lung cancer, emphysema, bronchitis, poor circulation, have stinky breath, have interrupted sleep because of inevitable nicotine drop about three hours into sleep every night, and other problems. Besides the fact that they look just plain idiotic, smoking like adult babies dependently sucking on a lollipop in public.
Where is the self-control?
How are there frum wife-beaters, ganovim, sex addicts, liars, and drunks? I am not condemning the people, just pointing out that there is a reason that these awesome mitzvos often do not turn us and others (with problems such as the above) into regimented, controlled adults. In fact, in our cases, the entire avodas hamitzvos becomes a vehicle through which our behavior intensifies, becomes like a burr in the cotton and cannot get pulled out. How?
My experience in this teaches me that it is because these mitzvah behaviors are ritualized. So we become 'immune' to them. Their cognitive effect becomes nullified because we do them because that is what is expected of us. Not out of self control. In fact, the self controlling is ejected, because being tempted itself is viewed as an evil, goyish, yuch.
Now, the RMB"M took pains to change that in Hilchos teshuvah, differentiating these mitzvos from moral issues, and trying to make clear than within the heart of the Yid, he or she keeps kosher (and issur ervah) even though he or she recognizes that it'd feel nice. He refrains only [b]because G-d wants him to[/b], period (no pun intended there!). But we have created a culture around them, and that immunizes us to the moral effect that Hashem 'intended'.
Now I am not arguing for reversal of that, at all. It works for the masses. Just like the nusach-tune of tzibbur davening makes davening rote, rote, rote (yuch) - but definitely preserves it from generation to generation for the masses. All I am pointing out is that on a personal level, it neuters an important aspect of avodas Hashem in the mitzvos.
So what to do? Abandon nusach-tune in shul and just say the tefillos (the way R' Yaakov Kaminetzky z"l used to daven)? Abandon doing anything because "that's just what Yidden do"? No way Jose'!
What I am trying to pass on is that as addicts, we need something more - I need something more. We need the penimius, the relationship, the hachno'oh that is in the mitzvos lo sa'aseh. If it will be po'el on us, we must be aware of it and try to face it and use it that way. To be more aware of the fact that I do not touch my wife when she is a niddah because I choose to do what Hashem knows is best right now. Na'aseh venishmah to Hashem. Not to culture - even Jewish culture - but to Hashem as He expresses it through His Torah and tzaddikim. It is a choice, and this is what he wants me to do - bechirah.
Yes, there is a place for hechrech, kofoh aleihem hahar kegigis - but not if I want to grow through the mitzvos lo sa'aseh by being aware that I could do it, but choose not to, because I accept that He knows what's best. I feel sure that xyz would be in my best interest, but I am wrong - He is right, cuz he is G-d.
So. About sexual abstinence in marriage. Hashem asks us to do it, and we live OK without sex for a few weeks...at least some of us do....but as soon as she comes home from the mikkie, sex is typically no longer optional for people like us, at all.
Where is all the self control we were mekabel/learned during the past two weeks?
It was never there. We were not really refraining because Hashem commands it, but because of cultural reasons: our wives would not tolerate being married to a sheygitz who would mess with her during niddah c"v, we were deathly afraid of koreis c"v, habit, or other reasons. All Ok reasons - but they do not work for addicts like us - like me. They do not inculcate in us anything like self control, hachno'oh to or acceptance of/devotion to Hashem's Will for us. They will not even touch our sexuality, at all.
I gotta go now, but so far, do you hear where I am coming from? Please leave the next conclusions out of the matter - just till here, do you hear me?
