The sexiest thing a man can do is follow through
Just doing what you said you were going to do, when you said you'd do it.

That's it.
I spent years in relationships where I was good at the gesture and sloppy with the follow-through. I meant well. I was enthusiastic. I also left a trail of small broken things that added up…
Apparently women go positively crazy for proof that you're someone they can believe and trust.
Do it without asking.
I've watched men spend years trying to be more attractive, more interesting, more something. Most of them could have skipped all of that and just started keeping their word.
Here's the mechanism. Her nervous system is not evaluating your intentions. It doesn't have access to your intentions. It only has access to your behaviour over time. Every time you said you'd do something and didn't, her system logged it as a safety calculation.
Can I relax around this person, or do I need to stay alert? When you follow through consistently, you are not just being reliable. You are changing her baseline. She stops bracing. Attraction feels like relief for women, they get to relax and not think.
And to be honest, most men were also conditioned out of this early.
You got praised for your ideas, your potential, your enthusiasm. Nobody checked back in two weeks to ask if you did the thing. So you learned to perform commitment rather than carry it. You got good at saying the right thing and fuzzy on the follow-through. That pattern shows up in relationships and she feels it.
