CMV: A man's "creepiness" is often based on how attractive/unattractive the female observer/participant finds him.

Women are often put off by men they find unattractive, even during entirely mundane interactions.

Oftentimes, something that is considered creepy when one guy does it, is considered cute, quirky, funny, hot, confident etc... when a different (and always more conventionally attractive) guy does it.

This subjective and fluid definition of creepy seems to be causing more and more men to withdraw either partly or entirely from some interactions with women.

This is not to villainize women - women are also treated differently based on their looks. However, this particular question is about most women's fluid/non-objective definition of 'creepy' men.
