There's other ways. Ask them for their passwords, ask them to hand their phone and riffle through their conversations and photos. If I know they won't be offended them I'll ask them to send me nudes or if they would let me put a camera in their shower. After all, if you're have nothing wrong you have nothing to hide, so why should you close your shower curtain?
