I'm 13 my dad is a triplet and 2 of 3 of them are gay (my uncles not dad) but I'm also gay we all go to a baptist church all of us my uncles grandparents siblings everyone and we're fine with them being gay just I don't know how there gonna react to me being gay.
I think you have a very good chance of them loving you just like they do now! I think open means open! Hugs-CK
