Considering that you find your wife physically attractive:
If your wife is still stateside with you, make arrangements to spend the weekend in a posh hotel with her. Make one simple rule, all time inside the room is to be spent completely naked. No exceptions.
Make sure that you have a ready supply of your favorite beverages, fruits and chocolates.
Whether you make love or not over the weekend, get used to being with each other naked. I bet you won't make it a day without having sex.
One thing you should understand about porn, very few people actually enjoy sex the way it is depicted in porn. Even fewer practice sex the way it is depicted in porn. Porn is nothing more than sexual entertainment, there is little that is real about it. If you are expecting your wife to perform like a porn actor, then you seriously need to gain some understanding about what sex with a normal woman is like, and especially gain some understanding of female sexuality. If you study normal sexual behavior, then over time, you will find the act of sex/love making between two people quite fulfilling, yet leaving you wanting even more.

I will ferret out an affair at any opportunity.
-An affair is the embodiment of entitlement, fueled by resentment and lack of respect. -An infidel will remain unreachable so long as their sense of entitlement exceeds their ability to reason.
