Your half-siblings, do they look like you?

Did you notice that you were particularly attracted to any of your half-siblings?
But I don't feel attracted to them, I mean, I only really feel attracted to someone based on their personality. And once I learn someone is my sibling, I think I'm influenced to not be attracted to them hahahaha
