Sex repulsion affecting personal life

I’ve been a SWer of different flavors for about a decade, and I’m finally at the point where I’m feeling active sex aversion and repulsion. I genuinely don’t know how to start fixing this, because I don’t want to feel gross, dirty and ugly when trying to fuck my wife. Do any of y’all have any tips on how you were able to move past these feelings? I know that therapy is the ultimate answer which is something in the works, but if anyone has any helpful tips in the meantime it would be highly appreciated.
