In my personal experience, the worst thing that could happen is to receive a no from someone you’re already expecting to say no. My father was this sort of Mexican stereotype of a macho man and for years I kept my preferences a secret from him, thinking the worse could happen. Everything turned out well. He found out by accident after a sibling tried to assault me (a story for another day I guess), and he just let me know that it was fine for him. He said, and I quote “Son, I’ve gone through an infinite amount of stuff in life. This won’t surprise me nor make me love you less than I already do. You do you, and that’s fine to me.”

That being said, everything can happen. Give it a chance, and remember that family is the one that has your loyalty. It will be hard at the beginning if things don’t turn out right, but there’ll always be someone who cares for you and loves you. I presume, that is, what a true family looks like. You’re very brave and it takes lots of courage to come out with someone so beloved as parents are. I wish you the best of lucks!
