Is it okay to have a male GOMG oc?

So basically I made a Magia Oc,he's name is Star but he's magical boy name is Magical boy name is Magia mecha.But Idk if it's okay to have a male GOMG oc,because I saw a post saying that there aren't any guys in the anime or manga but then who slaps Azure's butt in the anime which makes her feel the sting?
