Nut isn't a waste product like feces, urine, or sweat. Nor is it designed to remove, store, or get rid of bacteria like snot or earwax. It's literally a product of sex. I never understood why people were so grossed out by it.
I never understood being bothered by it, after blasting off on each other me and my x would fall asleep in the drying remains of our love babies and clean up in the mornings.
I'm not grossed out by it, but I could see why others could especially if they don't know them well. It's a bodily fluid that isn't the same for everyone. STDs are a result of sex...nobody wants those either.
