Is anyone else weirded out by communal sponges?

I was thinking about sponges as I was washing dishes a few minutes ago, and I started thinking about how the sponge at my work, which people use mainly just to clean their coffee mugs, grosses me out…I never use it, even when there’s a new one. I always just use paper towels. And then I remembered how, when I was dating this guy about a year ago, I was absolutely grossed out by the sponge he and his roommates used to clean their dishes—again, even if it was a relatively new one and didn’t have stains on it. Something about shared sponges just weirds me out, and I’m not even sure why…does anyone else have this issue?
