same with me, almost nobody in my extended family knows, except for one aunt, who my mom told. (which i wasn't okay with) my aunts husband probably doesnt know, he's a meathead football type, and would probably make really offensive jokes. i have an uncle who i would tell, but for some reason i haven't. idk i dont see any point.
as for my grandparents, same thing, my mom told me my grandma thinks bisexuals are perverted. which is fucked up. my family is cool enough to accept it, and even joke about it. i join the jokes too, but my dad hates the jokes. even though i know he loves me, i'm betting he hopes i marry an Eve, not a steve
so yeah, same thing.
