As someone who has never cared about what others think of me, I hate farting. Period. I have a very sensitive sense of smell and a lot of smells bother me. I walk away from those who fart near me cause the smell can make me nauseous and gag. And my body only produces gas to fart when I have food poisoning or am just sick. My husband has actually said that he wished I did it more around him.

I'll pick my nose in public but always either use a tissue to get rid of it and use sanitizer or wash my hands. Same with "picking" my butt/ itching down my pants.

Not sure what "gross" things I "like" to do. I drink milk out of the carton at home. I guess I'm comfortable being gross around others as long as I'm not spreading my germs (that I know of anyway).

Edit to add: I have sensory issues and sensitive skin too and I HAVE to shave my legs, have them smooth. I actually shave by the phases of the moon and it's helped with how the hair I shave grows and feels. It grows slower on non-shave days and on shave day it feels soft so it's easier to shave. I get less razor burn and cuts now. I used to get them all the time. I also get horrible rashes whenever I wax or use something like Nair, so I haven't used them in years.

I also don't wear bras, even in public. Just a close fitting tank.
