Doc,
Just so we're clear: First off, I cleared all of my comments first with Rav Gellar. All those remarks were my words that he approved, or his own words that I typed as he spoke. So any criticism is ostensibly being registered against his da'as Torah, which is not a prudent course for a Yid.
Secondly, if you re-read my comments, you'll see that I was directing my statement largely to cordnoy's assertion that "channelling our libidos to our wives is probably a recipe for disaster." Most of what I was saying pertains to married men focussing their sexual drives solely upon their wives, and using Torah, Teshuva, and avodas HaShem to sublimate the yetzer hara to holy activities.
An unmarried bachur (a) needs to focus purely on the latter, and (b) take a wife as soon as he is able, so that he may direct his sexual passions to a kosher kli kabala.
Thirdly, don't read too much into what I didn't say. I choose my words pretty carefully. And for many kinds of people, HaShem has been m'zakeh me to be a highly effective and successful marriage counselor for hundreds of people. Baruch HaShem, He has been m'zakeh me with around a 90% success rate, bli eyin hara. The reason, too, is because I listen very closely to each party, hone in on their problems, get them to reach concurrence as to what the problems are, and then zero in on it, and tell them exactly what they must do -- at times calling my rabbaim for advice as to how to handle it. People come to me precisely because I'm a straight shooter, and they tell me that my reputation as such is what they want.
Lastly, and here's the come to Moses moment: I think it is a mistake to see our shared problem in the same light. Though we might have the same struggle against histaklus asuros, we each have a different nisayon. I don't know about you -- if you are FFB, grew up with or without a TV, girlfriends, lack of tsnius around the house, etc. I grew up totally frei. As such, I did not stumble into this problem, rather I was born into it. I grew up in a totally secular, permissive home with erotic literature and films abounding. I found my first dirty magazine when I was ten, had a pool in the backyard, grew up with lots of women who were friends of my mom, who would come for a swim, and all the voyeurism that that entailed. I was (am) a very attractive man, who had lots of girlfriends, cars, booze, etc. In short, I grew up in a totally menuvaldik environment with open sexuality, nudity, pornography, and licentiousness. I did not pursue this ta'avah for znus. It surrounded me for 25 years. So this is a struggle into which HaShem was megalgel me. The fact that I was able to realize the issur, and formulate an approach to grapple with it is a shevach, in my Rav's words.
The specific question you asked, regarding a wife who refuses to be intimate now with her husband because of his moral failure -- that is a completely different parsha altogether. Moreover, it is a highly individualized matter, and each couple will need to be counseled differently.
In my case, my wife was never moredet. She busted me once, and knew of my struggle, but she also understood that she was a small part of the problem, and a huge part of the solution. That is often the case. She looked at it as her problem too. She grew up in a much less promiscuous and permissive environment, and is far more prude than other women who grew up non-Orthodox. But she also has enough seichel to know that it HaShem gave her a husband who loves her tremendously, but who has this weakness. She has her own shortcomings, which I compensate for, too. Obviously everyone's situation is different and unique. Not every man's wife is going to rebound from the shock and shame, and take it upon herself to be part of the resolution.
But b'etzem, I can tell you categorically that, having spoken to various chashuv Rabbanim on the inyan, the da'as Torah ostensibly holds the metsiis is as I have depicted it. Yes the bechira and inner milchama is ours; yes we are ultimately the responsible party; yes it is our neshama, and our aveira; een hachi nami that this is so. However, there are many maasim and raayos from Chazal which specifically articulate that it is one of the tafkidim of the woman to rescue her husband from sin. She has a major role to play in the yeshua.
