For men?
Masculine guys are the stereotype. Muscly, low voice, football mad. Basically the old fashioned word for a lad I guess.
Feminine guys tend to speak with a camp voice, they’re skinny and care a lot about fashion/make up/ ‘girly’ stuff.
People don’t always fit into these two categories, they’re just stereotypes. Some people have aspects of both, some have none. You don’t have to fit into a box.
