Tallima: Now, I am a Christian. But that detracts from my statements.
I agree that religion is not a conducive topic for this particular discussion. While religion often does influence one's approach to sexuality (in all the various ways that exist in the range between Tantrism and celibate), one can have the same approaches to sexuality without adhering to any religion, so let's leave that out of the equation.
I do, however, think that you _also_ introduced aspects into the discussion that aren't conducive. That's an approach of "men are ...." and "women are ...", followed by very general statements that might represent your personal social environment, but its rigidity excludes a lot of the variety and differences that exist between humans.
As an example, my personal experiences of my partners' reaction to porn range from "You don't love me any more" to "I don't want you to watch it without me, but I'd LOVE to watch it together with you", to "Hey, do you have some girl-on-girl stuff?", to a woman who watched porn to scratch a particular itch that I couldn't cater to because it touched one of the very few taboos I have. I would never even
dare to try to make a statement about "all women", or even "most women", because in my experience, reality is much more versatile and varied than the simple and clear-cut categories we might feel comfortable in.
So, if you abstain from porn for the reasons that you explained, you have my respect for that, and given your description, it certainly sounds like the right thing for you and your wife.
However, please be aware that others might feel offended by being told that (for example) they would be lying simply for stating that something which they enjoy doesn't affect them negatively. It's possible that you, with your background, can't imagine a different approach - but that doesn't mean that such different approaches don't exist, aren't just as valid as yours, or aren't even the better choice for people who happen to just be very different from you in this regard.
