Couldn’t get it up

As the subject says, I couldn’t get it up for my 38+1 wife. We utterly adore each other. Stereotypical “more in love today than we were yesterday”. Definition of my most incredible, beautiful, best friend. We’re usually like 🐰🐇

Something just didn’t work and I feel incredibly dejected and she of course it’s pretty down herself. Anyone have experience with this and could possibly share how you dealt with it?
