Are you going to work on yourself more? Are you going to separate/divorce on the chance that you will find your perfect (or close to perfect) mate?
Chances are you can find a new relationship which is more sexually satisfying but is lacking in other areas. As long as you can look in the mirror and say "I've done all I can to improve myself. I cannot change HER, but I've improved me all I can so now it's time to make that choice."
What's your choice? Take your time, you have the rest of your life if you want to but don't whine about being stuck. You have control of your sex life, not your wife. If you want improvement and she doesn't then it narrows your choices considerably. What are you going to do?
