Identity chrisis

So my LGBTQAI+ identity has aways been confusing. Since the age of like 8 people have been calling me lesbian for the way I act and dress but it was never the kids i spent everyday with or atleast they havent spoke it. My sibling and this cousin person ish thing keeps calling my lesbian 🙄  and BOY a few months ago I was in my 8th grade homeroom just reading in my desk AND THESE GIRLS they always try to guess peoples sexualitys and some girls who DONT do this chimed in and said they thought I was lesbian in the beginning. AND IDK WHY PEOPLE THINK THIS. Maybe because I never talk about boys or really anything of that nature makes me uncomfortable (BUT I MEAN THEY ARENT HALF WRONG) 🏳️‍🌈
