When you're interacting with guys, whether it's one that you're dating, a friend, an acquaintance, or a total stranger, there are almost certainly things that they're going to do from time to time that you register as, well, a little bit creepy. Sometimes, those things that you think are creepy are actually creepy, but other times they might not be quite as creepy as you may have initially thought. There are many things guys do that you think are creepy, but are actually pretty normal. Sometimes, though, the context really matters. What they're doing might be something that you find creepy if you hardly know them or aren't romantically-linked, but wouldn't be nearly as creepy (or would even be totally normal) if the situation were different. This is subtle creepiness.
Not only that, but in some cases, you wouldn't find it creepy if a woman did these exact same things, whether you knew them well or not. Context — and societal influences — can make all the difference. Many women are taught from a young age to be warier of strange men than they are of strange women. That's definitely not to say that they should automatically get creeped out by men or shouldn't ever regard a woman as creepy, it's just that they've somehow been told, through words or actions, that there's the potential for greater risk. Many of these things aren't actually really that creepy, they just can occasionally seem to be. Follow your instinct, of course, but also don't get too worked up over these supposedly creepy things. They're actually pretty normal.
