I know people who share a toothbrush with their significant other, and I just don’t get it. To me, it’s disgusting to share a toothbrush with anyone, whether you’re dating/married to that person or not. I mean, you remove plaque and germs and other nasties from your mouth with that thing. Do you want someone else sticking that in their mouth? Would you want to put their toothbrush in yours? I’m sure someone will come along and point out that if you’re sharing bodily fluids with them on a regular basis, using the same toothbrush isn’t that much more disgusting, and I would have to respectfully disagree. You don’t clean your teeth with a dick. Last time I checked, anyway. Vaginas are not known for getting bacteria out of your gums. Don’t be one of those people. USE YOUR OWN TOOTHBRUSH, AND DON’T TOUCH MINE.
