Do you get upset when your sibling or family member goes through your phone without your consent?

Do you think it's a violation of privacy? I would never do that to anyone but I caught my sibling, who's 1 year younger than me if that matters, going through my phone and I just felt completely upset and violated because I have nudes of my boyfriend and my nudes on there too.. what would you guys do in this situation?
