Anyone else have internalized biphobia?

I came out as a lesbian because I thought no one would take my attraction to girls seriously if I came out as bi because of the whole “bi women are just confused straight girls” stereotype. I’m out as bi to my friends now, but I don’t wanna say anything to my mom because then she’ll be trying to set me up with a guy every two seconds and act like me being attracted to any other gender than male was just a phase I grew out of.
