[Discussion] How are these erotic writers able to create such believable female characters?

**Warning:** If you don’t want your fantasy bubble broken, do not read any further.

Okay, let’s be honest, a good amount of these erotic work are created by guys for guys. How do these male writers able to create such believable female characters (including fantasy ones) without being a girl themselves? Specifically, the dialogue. It makes you believe it is in fact a girl talking, not a transvestite. It blows my mind how they’re able to trick us that well, or do they hire a female writer to write the dialogue for the female characters?
