ELI5: What goes into mens' cologne that makes them smell "manly". What about these fragrances/chemicals makes them masculine?

It's contextual. In western culture most women's perfumes have fruit, flower, and vanilla notes. Men's cologne generally have earthy notes like pine and musk. 

By context you think of it as smelling one way or another because you've always associated certain smells with perfume and others with cologne.
