You never know what effect it will have CeMar until you try it. Giving someone kudos for a job well done makes them feel valued by you...feeling valued by you can give them the warm fuzzies for you, the warm fuzzies can lead elsewhere...but unless you take the first step in trying to find out where it will go....NOTHING will happen. Not to mention you aren't doing that to INCREASE her sex drive but to make her feel valued by you. How do you think anything will change if you don't speak her love languages? You are wanting her to speak yours after all aren't you...well YOU have to be the one to start that.
You are a religious man CeMar, THAT in itself is a huge leap of faith...why can't you give your wife that same benefit and take a leap of faith in trying to get your marriage to a better place?
Your comment about giving WOA's to your W is a very cynical response...if you have that view towards her and trying things, why wouldn't she have that same view towards you? I HAVE experienced & viewed first-hand the effect WOA's have on a person, not just in my own marriage either, but in a friend's.
