English is at the de-grammarised end of the spectrum. There are gendered clues in English, but they're (mostly) not baked into the grammar. The differences are more about specific idioms and expressions that one gender is more likely to use, and they're really a kind of variation on other subgroup slangs - like teen slang, other age-related indicators.
Most languages have far more obvious grammatical distinctions. The Romance languages have obvious gender in the grammar, but it's... just there. It doesn't do much except to indicate that the subject or object is male or female. Beyond that, there are some rather random associations of gender to specific nouns.
Fully distinct dialects/languages are incredibly rare and are often artificial and/or more likely to be created by a subculture than as a direct result of gender differences.
Example: English has Polari, which was entertainer/street slang and often used in gay subcultures. It also has Cockney, Estuary, Northern, Scottish, Urban, and others - all differentiated by culture.
