do you prefer the woman to have kids, or no preference?

I don't really have a preference. That said, a female AP with kids can understand how unexpectedly bonkers one's days and nights can be a bit more than an AP without kids.

Also, does having kids change the way you view her sexually (either positively or negatively)?

A female AP without kids tends to be a bit more out there when it comes to the way she dresses, dressed in the latest fashion trends the way a single person would. But there's something so attractive about a female AP with kids and the way she dresses—looking comfortably beautiful doing even the most mundane things like dropping off the kid(s) at school or standing in line at the supermarket. She looks good regardless of whatever tf she wears.
