There are a lot of little things that you do each and every day without giving much thought as to what, if anything, other people think about them. And because of that, you're likely doing things each day that are sweet, attractive, or endearing without even knowing it. Some common things you don't realize men find really endearing, according to science, for instance, are things that you do all the time, in so many different settings, and around so many different people. They're things that you do without even trying, but they're also things that have a foundation in science for as to why they work.
Laughing, blushing, accidentally bumping into something or spilling the contents of your bag, and laying your head on their chest are all things that you might do without thinking (or without being able to even control it) that men find endearing and that make you seem more human, more relatable, and more approachable. Nobody is perfect and some of these little things can make you seem even less so — but in a good way.
Ultimately, being yourself, for better or worse, can help endear you to others (not just men) because it let's the world see who you really are, quirks and all.
