I'm going to have to read this a few more times before I understand it fully, but I want to address one thing right away:

For example, how many Republican senators and Baptist ministers would you guess have sworn mighty oaths to never have gay sex...what you have done sets up an expectation that a single failure will lead to the destruction of someone's entire life... and that is NOT a responsible thing to suggest or prime, EVER.

The way I dealt with this was to make my oaths in one month blocks. So the Republican would have to swear "I won't have any gay sex...this month." Even for the most lustful, this should be possible.

If, at the end of the month, this was so painful he wants to just give up on this, he can. Or if he thinks he can do it, he could also include the statement in his next month's oath.

What I found was that there's a very different mental feeling between "I can never do this again" and "I have to wait a month to do this." The latter is annoying but bearable, and it's why I included the "never make an open-ended oath" point up there.

(if you want to test this for yourself, but don't have any repressed homosexual urges, masturbation makes a good test case)

I don't think this technique is at its best for something where doing it once is a disaster, like gay sex for Baptist ministers. I think it's better for something like dieting. Tell yourself you won't eat cookies the whole month, do it in the full knowledge that you'll start eating cookies again when the oath runs out, pig out on cookies for one day, and then when you have no desire whatsoever for any more cookies, swear to diet again for the next month.
