Is it a turn off if I don’t know how to flirt?

Literally I don’t know how to flirt 😭 so I dreamt about this guy who kissed me on the check and we’re on his bed not doing anything dirty. I told about the dream and he’s like I have a tendency to make things a reality. And well I really don’t know what to say to that. And I want to flirt back but not to where it’ll seem like I want sex. Just enough for him to know that I do like him 😩 I’ve been through some stuff and always put a shield up and never allowed my self to be myself around a guy and I think that’s why I can’t flirt. So do you guys find it unattractive when a girl won’t flirt back?
