Frankly, I personally see my CF views (and I know this isnt exactly popular around here) as "vacation versus vocation": I'm actually quite good with kids and always enjoy time with them, but I found in my heart that there is a very clear difference between a few minutes and a life sentence, and I know I'm too selfish and ambitious to not eventually resent any children for affecting my life options.

I always kinda figured I would never find a CF woman and would eventually have to swallow any reservations, but I was incredibly lucky in finding a proud CF woman and I have made the decision permanent.

It all depends on the relationship, but in my experience it usually comes up in the first few months how you feel about kids; being strong in your stance will be a repellant to those you would be wasting your time on anyway, and a beacon for those that are also CF, so get it out there early
