This keeps getting brought up, but I don't think it's at all realistic. The more likely scenario is that she reacts like the majority of women (and men) who aren't 100% self-confident, and starts a huge fight. Part of being an adult is learning not to voice inappropriate thoughts. Talking about sleeping with family members is definitely not appropriate. What if you found her mother attractive, or her grandmother? Would you say the same thing? If not, then you're still filtering yourself.
