I changed plenty of diapers and it never bothered me - too much. I’m also the one that cleans up any spills or animal messes in the house.
My wife takes care of elderly people - yeah, I hope it is a long time before I have to do what she does.
She is also fine with sticking her fingers in the dog’s ears to clean all the goop out. I hold the dog, mainly so I don’t have to do what she does!
You should worry most that there will be someone there to do it for YOU :-)
