Is it possible to blacklist only male, because when I try it gives a whole category male?

you can if you want to blacklist posts that only include male characters you can try adding:

male -female -intersex -ambiguous

to a line. this will only block posts with male characters unless there's a character of another gender category in the post, you can remove any of these if you want to (-intersex can be split down to "-gynomorph -andromorph -herm -maleherm" if you want to exclude any of those).

also, Dragonlord2328's suggestion of male_focus is probably a good one.
