Cats cleaning each other

[I_love_cats]

Hello petlovers

I have three cats, two are males and one female. Toby and Joey are always cleaning each other but my female girl, Sabrina doen't clean my males cats and when Joey wants to clean her head, she won't let him. She gets mad at him. I love seeing them lick each other. I wondering why they lick each other, i didn't think males would lick each other. Doesn't anyones cat lick each other? My Joey he lick my face all the time but boy he has a rough toung but Sabrina never licks me, i wonder why she doesn't do that. I only see males cats lick. What do you guys think?
