For example, a Zodiasexual will only have sex in January with people born in January, and so on for February and beyond.
It is considered rape to hit on a Zodiasexual if your birth month does not match the current month.
It's also considered an act of violence to lie about your Zodiac sign in order to attempt to copulate with a Zodiasexual.
Person A: Hey, I was born in May, let's bang!
Person B: Sorry, It's June. You'll have to wait another year. I'm Zodiasexual.
Person A: Huh? Okay... I'll find a normal person.
Person A: I heard you're Zodiasexual. Are the stories really true?
Person B: Hm, sorry - what? I don't speak to non-zodiasexuals.
