Maschile vs. mascolino
While both maschile and mascolino translate to masculine or male, they are not interchangeable. Maschile is a neutral, objective classifier for sex, grammar, or general categories, whereas mascolino is a subjective descriptor for qualities, traits, or behaviors culturally associated with masculinity.

Summary
In essence, use maschile for objective facts and categories (sex, grammar, men's clothing). Use mascolino for subjective qualities and stereotypes (a manly voice, a masculine attitude, a tomboyish style). Maschile states what something is (a male individual), while mascolino describes what something is like (having manly characteristics).
