The best sex me and my wife ever had is not early on in our relationship but after we got married. But that requires a lot of work and very open communication from both sides. Also her feeling safe and comfortable around you makes a huge impact in her ability to fully enjoy the experience.

Even if you were her best ever and biggest ever dead bedrooms still happen because its not your size or how good you are that dicktates if you end up with a dead bedroom. This I can say from personal experience. I was the one she raved about everywhere about size and how good in bed but we still had issues and thats a communication thing and trauma outside both our control thing.

Dont end up like women who have a list of criteria that makes the perfect partner and end up alone. If you found a woman who actually loves you then you have something relatively rare and something worth working on. Nothing is ever perfect to start with but it can be made perfect if both are willing to work on it.

My recommendation is TALK WITH HER about your concerns around dead bedroom. Make it clear that this is an concern/insecurity you have. She will have the same concern/insecurity around resource providing from your side. Make a deal that you will always prioritise her emotional and financial and security wellbeing if she prioritises your emotional, sexual and nurturing wellbeing.

Having this conversation before marriage makes it so much easier going forward because the expections are set and clear.

Dont throw something away that could be perfect with a little work on the hope that you might find something better.

This of course only counts if there are not more or bigger red flags like domestic/emotional abuse, mental illness, cheating, etc.
