>>224722Yes, I also prefer having my own things that I can use exclusively. I don't like sharing things, especially food and drink. Drinking from the same bottle after someone disgusts me, and taking a bite of a sandwich or something is ever worse.
I wonder what's the common factor for people like us? Were you growing up in clean, almost sterile conditions? I was born through c-section, so I never swallowed mother's probiotic shit and sludge like babies usually do. I have this wild idea that most people's microbiomes are very diverse but more or less the same. They don't mind sharing food, kissing, licking buttholes during sex, because they have the same stuff inside anyway. But our microbiomes are unnatural, weird and different than most. Our gut flora mess with our behavior through the gut-brain axis, causing us to avoid changing the status quo in our guts.
