I didn't catch any suggestion that it would be strange to have sex but not want kids. I'd say that's probably the case most of the time when having sex. Options are given in the story to pull out and pregnancy isn't a given even if you don't. Risk sex is erotic too! As pointed out above I agree that the MC is aware of the consequences. I don't think he's taken a position on it at this point. If pregnancy fits the story I would enjoy a choice.And if you're into it, that's fine. I don't get it at all myself, but at the same time, I don't understand the desire to have children period, despite it obviously being a very natural thing, so to each their own. But the idea that it somehow doesn't make sense to want to have sex with someone and not wind up being responsible for another person until you're almost 60 (I'm guessing the MC is approaching 40, much like I am, considering he has a college-aged daughter) is a little silly.
