insertion in fiction

as someone who makes ocs i believe it is inevitable to somehow put tidbits of yourself and the people surrounding you into your ocs. all of mine are vaguely based off myself but recently i've been realizing that i am making. absurd amounts of metalhead ocs. and blonde ones. and the metalhead part, okay, sure, i consider myself one So that makes sense, right. But the thing is i used to preach about not liking blonde people ever and then i developed this horrible horrible crush/obsession on this guy [almost 3 years going strong] [he doesn't know my name] . And he's blonde. And a metalhead. And now i can't stop making blonde characters because i'm so insane over blonde people now and it is SICKENING!!!!
