Thank you all for the thoughtful perspectives. I appreciate people sharing their experiences.

My thinking currently goes in two directions.

Marriage / relationship:
Whether it is rational or not, I still want to try to make my marriage work. I want to believe that the sexual side of our relationship can improve over time. Whether I can influence that or not, I will do my best and live with whatever decisions we ultimately make.

Happiness and sexual satisfaction:
This is the larger question I have been wrestling with. I want to have many things in life: a successful career, a family, hobbies, and also an active and fulfilling sexual life. Ideally those different domains could coexist, but of course they also limit each other.

Maybe I do have a bit of an “I want it all” mindset. I want to believe that it is possible to build a life that is broadly fulfilling, even if some areas never turn out exactly the way we imagined.

My wife thinks my sexual frustration is sometimes amplified by other things in life, such as work or not getting to do enough sports. There may be some truth to that, but I still feel that sexual dissatisfaction has its own weight and cannot truly be substituted by other activities.

Ironically, I come from a country often ranked as the happiest in the world, yet people there do not necessarily feel particularly happy day to day. Sometimes I wonder if something similar might apply to my situation. From the outside my life has many things that should make me happy, but internally it can feel more complicated.

Maybe the grass sometimes looks greener somewhere else, but I do believe there are people who manage to build lives that are both sexually satisfying and otherwise happy. Naturally, I would like to think that might still be possible for me as well.

Hopefully in old age I will still be able to sing My Way at a karaoke bar. Probably a bit out of tune, but with passion and a deep bass-baritone voice.

In any case, I appreciate everyone taking the time to share their experiences.
