My boyfriend likes to watch weird videos about pus/wax

My boyfriend uses to watch pimple popping videos or people cleaning their ears, now he finding videos in his algorithm about people cleaning their pets nose to remove snot and wants to try on our pets. He says the pets look so happy after removing it and I tell him it's dangerous and to remove snot only if we notice our cat or dog breathing weird. I really don't want him to try any of these on our pets.
