Is anyone else's spouse with Lewy body dementia constantly after them about sex?

I am so sorry that you are going through this. I do not have this issue but I just feel terrible for you. Talk to his doctor??

You might want to locate a support group for caregivers partners of people with LBD. I'm sure you will find others with the same problem or other common issues. There is one such support group via Zoom from the Las Vegas location of the Cleveland Clinic Lou Ruvo Center for Brain Health. Good luck.
