That seems like an extreme place to go that would only seem justified if you can’t imagine wanting a seemingly ridiculous number of kids. So I’ll offer my perspective.
I grew up with an unusually large number of women in my extended family and heard them talk a lot about enjoying or wanting big families. Many of my cousins went on to have as many kids as they had hoped for originally, and they continue to have children, as if it’s a competition. I don’t get this, because I never wanted children of my own. But all I have ever heard is the woman’s side.
My impression in every case is that, if one of them is setting the agenda on the child front, it’s invariably my cousins. I’m not sure how that conversation goes, but these women are all conventionally attractive, and I would guess it doesn’t take much convincing to get unprotected sex from their guy if that’s what they want.
Long short, I’m not too worried about my cousins being tricked into pregnancy. I do sometimes worry that maybe the men (who have meek personalities by comparison, and look more tired each time I see them) might feel like they weren’t given much say, which could lead to relationship problems later, but it’s not really my business.
