If you aren't compatible sexually then you are not compatible.
I have been married twice. My first wife was practically my "soul mate", we had the same taste in everything. We were best buds, everything was perfect besides our sex life sucked. It always led to conflict and problems.
My wife now we have almost nothing in common when it comes to taste, art, music, hobbies, nothing. We have an amazing sex life though. I couldn't be happier.
That is not how it works in the movies. I am supposed to meet my first wife and live happily ever after. It is the difference between real life and fiction.
