You brought up something new in this post that I hadn't seen you bring up before. The idea that you could learn to enjoy sex with your wife. I do believe this is possible. In fact, it is actually quite common. In the absence of an adequate partner of the opposite sex, many heterosexuals learn to enjoy sex with partners of the same sex. Their primary sexual attraction will always be towards the opposite sex, but they can learn to have a secondary sexual attraction. In modern times, this phenomenon of situational homosexuality is observed primarily in prison populations. In times past, it was common to find this form of homosexuality existing among seafarers and other military types.

If it's possible for a heterosexual man to develop a secondary sexual attraction towards other men, I don't see any reason why a pedophile can't develop a secondary sexual attraction for women.

How you go about doing this is another question entirely, and not one I have an answer to. But as to the question of whether it is possible or not, I have no doubt it is; it happens in prisons across the world every day.
