"Things that lead to children and related activities are supposed to be something that men and women don't talk about with each other, at least not unless they're married or going to be and sometimes not even then. But, well, I don't see any other sources of information around, so if you have questions I will try to answer them. Just please don't ask anyone else questions about it unless they and the only other people who can hear you are women about your age or older who seem friendly. Adults aren't supposed to talk to children about it at all unless it's immediate family explaining things to immediate family, and a lot of people think it's rude or embarrassing even if the topic is raised among socially approved combinations of people."
